Abstract: International audience; Carbohydrates play a myriad of critical roles as key intermediaries for energy storage, cell wall constituents, or also fuel for organisms. The deciphering of multiple structural isomers based on the monosaccharides composition (stereoisomers), the type of glycosidic linkages (connectivity) and the anomeric configuration (α and β), remains a major analytical challenging task. The possibility to discriminate 13 underivatized isomeric trisaccharides were reported using electrospray ionization coupled to trapped ion mobility spectrometry (ESI-TIMS). After optimization of scan ratio enhancing both the mobility resolving power (R) and resolution (r), fingerprints from 5 different honeys were obtained. Seven trisaccharides with relative content varying from 1.5 to 58.3%, were identified. It was demonstrated that their relative content and/or their ratio could be used to ascertain origin of the honeys. Moreover, such direct approach constitutes an alternative tool to current longer chromatographic runs, paving the way to a transfer as suitable routine analysis.

Abstract: In this thesis, we investigate the vibronic (de-) excitation and dissociative recombination of CH+ by low-energy electron impact. We first develop a theoretical approach for the electron-impact vibronic (de-) excitation of CH+. In this approach, the fixed-nuclear R-matrix method is employed to compute electron-ion scattering matrices in the Born-Oppenheimer approximation. A vibronic frame transformation and the closedchannel elimination procedure in a spirit of molecular quantum defect theory are employed to construct an energy-dependent scattering matrix describing interactions between vibronic channels of the target ion induced by the incident electron. The obtained scattering matrix accounts for Rydberg series of vibronic resonances in the collisional spectrum. Cross sections for vibronic excitation for different combinations of initial and final vibronic states are computed. A good agreement between electronic-excitation cross sections, obtained using the quantum defect theory and in a direct R-matrix calculation, demonstrates that the present approach provides a reliable tool for determination of vibronic (de-) excitation cross sections for targets with low-energy electronic resonances. Such targets were difficult to treat theoretically using earlier methods. Within the same framework applied for the vibronic (de-) excitations, we further compute the cross section for low-energy dissociative recombination of CH+ coupling the outgoing-wave basis function defined by complex absorbing potential. The contribution of the three lowest X 1Σ +, a 3Π and A 1Π ionic states and the Rydberg series converging to those states are taken into account. The obtained DR cross sections are quantitatively in good agreement with the experimental measurements and exhibit a resonanc feature analogous to the experimental cross-section curve. The origination of the prominant resonances in the computed results are analyzed through computing the DR probabilities for the partial waves of the incident electron. The d-type partial waves including dσ, dπ and dδ are found considerably contributing to the DR of the ground-state CH+. This may explain the discrepancies observed between thoery and experiment in the preceeding studies.; Dans cette thèse, nous étudions la (dé)excitation vibronique et la recombinaison dissociative du CH+ par impact d'électrons de faible énergie. Nous développons d'abord une approche théorique de l'excitation (dé)vibronique de CH+ par impact d'électrons. Dans cette approche, la méthode de la matrice R à noyaux fixes est utilisée pour calculer les matrices de diffusion des électrons et des ions dans l'approximation de Born-Oppenheimer. Une transformation vibronique du cadre et la procédure d'élimination à canal fermé dans l'esprit de la théorie des défauts quantiques moléculaires sont utilisées pour construire une matrice de diffusion dépendant de l'énergie décrivant les interactions entre les canaux vibroniques de l'ion cible induits par l'électron incident. La matrice de diffusion obtenue tient compte de la série de résonances vibroniques de Rydberg dans le spectre de collision. Les sections transversales de l'excitation vibronique pour différentes combinaisons d'états vibroniques initiaux et finaux sont calculées. Un bon accord entre les sections transversales d'excitation électronique, obtenu en utilisant la théorie des défauts quantiques et dans un calcul direct de matrice R, démontre que l'approche actuelle fournit un outil fiable pour la détermination des sections transversales d'excitation (dé)vibronique pour des cibles avec des résonances électroniques de faible énergie. De telles cibles étaient difficiles à traiter théoriquement avec les méthodes précédentes. Dans le même cadre que celui appliqué aux excitations (dé)vibroniques, nous calculons en outre la section transversale pour la recombinaison dissociative à basse énergie de CH+ couplant la fonction de base de l'onde sortante définie par le potentiel d'absorption complexe. La contribution des trois états ioniques X 1Σ +, a 3Π et A 1Π les plus bas et la série de Rydberg convergeant vers ces états sont pris en compte. Les sections transversales DR obtenues sont quantitativement en bon accord avec les mesures expérimentales et présentent une caractéristique de résonance analogue à la courbe de la section transversale expérimentale. L'origine des résonances proéminentes dans les résultats calculés est analysée par le calcul des probabilités de DR pour les ondes partielles de l'électron incident. On constate que les ondes partielles de type d, notamment dσ, dπ et dδ, contribuent considérablement à la DR du état de terrain CH+. Cela peut expliquer les écarts observés entre la théorie et l'expérience dans les études précédentes.

Abstract: In the context of Tokamak fusion plasma, the gyrokinetic Poisson equation has to be solved on disk-like domains which correspond to the poloidal cross-section of the Tokamak geometry. In its simpliest form, this cross section takes a circular form but deformed geometries were found to be advantageous and are more realistic. We propose a taylored solver for the gyrokinetic Poisson equation on disklike geometries described by curvilinear coordinates. Our solver also copes with an anisotropic, locally refined mesh to model the edge part of the Tokamak and a rapidly dropping density profile. Multigrid methods can achieve optimal complexity for many problems and are among the most efficient solvers for elliptic model problems. Multigrid methods for geometries described by curvilinear coordinates are however less common. We present a taylored geometric multigrid algorithm using optimized line smoothers to enable parallel scalability. We propose an implicit extrapolation scheme for our algorithm to increase the order of convergence by using nonstandard numerical integration rules for P1 finite elements. We also use problem-specific finite differences, which numerically show the same order of convergence as their finite elements' counterpart, enabling a matrix-free implementation with a low memory footprint.

Abstract: The GBAR experiment aims at measuring the free fall of ultra-cold antihydrogens (neV).This implies the production of antihydrogen ions, which are obtained by two charge exchange reactions involving antiprotons and positronium atoms. The goal of this study is to analyse the possibility to increase the production rates of the antihydrogens and the antihydrogen ions produced, by assisting the two reactions with a laser. The cross sections are obtained in the antiproton energy range of the GBAR experiment (1 - 10 keV), by using a semi-perturbative approach proposed by Byron and Joachain. This method,simultaneously, allows the description of electron-atom interaction (Coulomb Born Approximation or Continuum Distorted Waves - Final State), the electron-laser interaction (Volkov states), and the laser-atom interactions (first order time dependent perturbation theory). The positronium excitation from the 1s state by one-photon virtual transition process is studied, by considering lasers whose wavelengths are around 243 nm (Lyman-αline). It is then proposed to adapt these laser sources in order to excitate 3s and 3d states (Paschen-β). The Doppler shifts resulting from the positronium cloud velocity distribution are taken into account as well, at the confinement energies of 25 meV and 48 meV. Finally,the number of antiparticules produced is estimated. Compared to the case of non-assisted collisions, the losses induced by the photo-ionization and photo-detachment processes are evaluated.; L’expérience GBAR vise à mesurer la chute libre d’atomes d’antihydrogène ultra-froids (neV). Cela implique de produire des ions d’antihydrogène, obtenus à l’issue de deux réactions d’échange de charge faisant intervenir des antiprotons et des atomes de positronium. Le but de ce travail est d’étudier la possibilité d’augmenter les taux de production d’atomes et d’ions antihydrogène produits, en assistant les deux réactions par laser. Les sections efficaces sont obtenues aux énergies d’antiproton de GBAR (1 - 10keV), en utilisant une approche semi-perturbative proposée par Byron et Joachain. Celle-ci permet de décrire simultanément l’interaction électron-atome (Coulomb Born Approximation ou Continuum Distorted Waves - Final State), l’interaction électron-laser (états de Volkov),et les interactions laser-atomes (premier ordre de la théorie des perturbations dépendantes du temps). L’excitation depuis l’état 1s du positronium par le processus de transition virtuel à un photon est étudiée, en considérant des lasers dont les longueurs d’onde sont proches de 243 nm (raie Lyman-α). Une adaptation de ces lasers est ensuite proposée afin d’exciter les états 3s et 3d (Paschen-β). Les décalages Doppler résultants de la distribution de vitesse du nuage de positronium sont également pris en compte, aux énergies de confinement de 25 meV et 48 meV. Finalement, le nombre d’antiatomes produits est estimé. Comparativement à la situation où les collisions ne sont pas assistées par un laser, les pertes induites par les processus de photo-ionisation et de photo-détachement sont évaluées.

Abstract: Because the irradiation damage is a major challenge of nuclear materials, it is of upmost importance to accurately calculate it with reliable uncertainty estimates. The main objective of this thesis is to develop and improve the methodologies for computing the neutron irradiation-induced displacement damages as well as their uncertainties. After a brief review on nuclear reaction models and primary radiation damage models, we propose a complete methodology for calculating damage cross sections from different nuclear reactions and the subsequent calculation of Displacement per Atom (DPA) rates.The recoil energies from neutron-induced reactions are summarized with an estimation of the relativistic effect and the target thermal vibration. Particularly, a new method for computing the recoil energy from charged particle emission reactions is proposed by considering both the quantum tunneling and the Coulomb barrier. Some methods are developed to improve and verify numerical calculations. Damage cross section calculations from neutron radiative capture reaction and N-body reactions are also thoroughly analyzed and discussed. In addition to the neutron irradiation-induced displacement damage, the electron, positron, photon-induced DPA cross sections, as well as the beta decay and Fission Products (FPs)-induced damage are also investigated. Orders of magnitude of their relative contributions are given.For the neutron irradiation-induced DPA rate calculation, attention should be paid when using infinite dilution cross sections. E.g., in the ASTRID inner core, the self-shielding correction on ECCO 33-group damage cross sections leads to a 10% reduction of DPA rate, whereas the multigroup correction is still not automatically treated for DPA rate calculation in neutronic codes nor for computing Primary Knock-on Atom (PKA) spectrum. Based on the presently proposed method for computing the FPs-induced DPA by atomistic simulations, the peak value of the FPs-induced DPA rate can be 4 to 5 times larger than the neutron-induced one in the cladding of the ASTRID inner core, even though the penetration of FPs in the Fe-14Cr cladding is less than 10 µm. Therefore, the question of whether the FPs-induced damage should be considered for determining fuel assembly lifetime in fast reactors needs to be discussed.In the reactor vessel of a simplified pressurized water reactor, the covariance matrices of 235U prompt fission neutron spectrum from ENDF/B-VII.1 and JENDL-4.0 respectively lead to 11% and 7% relative uncertainty of DPA rate. Neglecting the correlations of the neutron flux and PKA spectrum results in an underestimation by a factor of 21. The total uncertainties of damage energy rate are respectively 12% and 9%, whereas an underestimation by a factor of 3 is found if the correlations of damage cross section and neutron flux are not considered., Étant donné que les dommages causés par l'irradiation constituent un défi majeur pour les matériaux nucléaires, il est nécessaire de calculer précisément ces dommages conjointement avec l’estimation de ses incertitudes. L'objectif principal de cette thèse est de développer et d'améliorer les méthodologies pour calculer les dommages induits par l'irradiation neutronique ainsi que de proposer une méthodologie pour l’estimation de l'incertitude. Après une brève revue des modèles de réactions nucléaires et des modèles de dommages d’irradiation primaires, on propose des méthodes complètes pour calculer la section efficace des dommages à partir de différentes réactions nucléaires pour calculer du taux de Déplacement par Atome (DPA).Une interpolation améliorée est proposée pour produire la valeur de crête de la distribution d'énergie-angulaire à partir de données tabulées. Les énergies de recul des réactions induites par les neutrons sont résumées avec une estimation de l'effet relativiste et de la vibration thermique de la cible. En particulier, une nouvelle méthode de calcul de l'énergie de recul des réactions d'émission de particules chargées est proposée en considérant l’effet tunnel et la barrière Coulombienne. Certaines méthodes sont développées pour améliorer et vérifier les calculs numériques. Les calculs de la section de dommage provenant de la réaction de la capture et des réactions d’émission de N-corps sont également analysés et discutés en profondeur. En plus des dommages induits par l'irradiation neutronique, les sections DPA induites par les électrons, les positons et les photons et les dommages induits par la désintégration bêta sont également étudiées.Pour le calcul du taux de DPA induit par l'irradiation neutronique, il convient de faire attention lors de l'utilisation de sections à dilution infinie. Par exemple, dans le cœur interne d’ASTRID, la correction d'autoprotection sur la section DPA de ECCO 33-groupe conduit à une réduction de 10% du taux de DPA, tandis que cette correction multi-groupe n'est pas toujours automatiquement traitée pour le calcul de DPA dans les codes neutroniques ni pour le calcul du spectre Primary Knock-on Atom (PKA). En plus des dommages par les neutrons, une méthode générale est proposée pour calculer les dommages de déplacement induits par les Produits de Fission (PFs) avec des simulations de collisions atomistiques. Elle montre que la valeur de crête du taux de DPA induit par les PFs peut être 4 à 5 fois supérieure à celle induite par les neutrons dans la gaine du cœur interne d’ASTRID, même si la pénétration des PFs dans la gaine Fe-14Cr est inférieure à 10 µm. Par conséquent, la question si les dommages induits par les PFs doivent être pris en compte pour déterminer la durée de vie des assemblages combustibles dans les réacteurs rapides doit être discutée.Dans la cuve d'un réacteur à eau pressurisée, les matrices de covariance du spectre de neutrons prompts de fission de 235U venant de ENDF/B-VII.1 et JENDL-4.0 conduisent respectivement à une incertitude de 11% et 7% du taux de DPA. Négliger les corrélations du flux de neutrons et du spectre PKA entraîne une large sous-estimation d’un facteur de 21. Les incertitudes totales du taux de dommages sont respectivement de 12% et 9%, tandis que les nulles valeurs des corrélations de la section efficace de dommage et du flux de neutron conduisent à une réduction de l'incertitude par un facteur de 3.

Abstract: Oxygen belongs to the group of the most important isotopes in the nuclear data field. The aim of this paper is validate various oxygen nuclear data libraries in different scenarios with high content of oxygen. For this purpose, fast neutron spectra were measured by a stilbene scintillation detector in the region of 1–10 MeV in the three model cases involving 252Cf neutron source and light water reactor. The cases include measurements of leakage spectra using 252Cf neutron source placed in the centers of the light water and heavy water spheres of 0.30 m diameter. Following measurements were carried out inside the concrete biological shielding of the VVER-1000 mock-up simulator in the LR-0 reactor and in the dry channel located in the center of the special core placed in the LR-0 reactor. In the case of the special core, symmetric active core consisted of six standard fuel assemblies which surround the experimental dry module, where the fast neutron spectrum was measured. The measured neutron spectra were compared with MCNP6 transport code calculations in ENDF/B-VII.1, ENDF/B-VIII.0, JENDL-4.0, and IRSN 16O nuclear data evaluations. Experimental results for all cases follow similar trend. All considered libraries underestimate experimental measurement in the region of 3–4 MeV in all cases.

Abstract: International audience; Terbium is one of the most interesting elements for new potential theranostics applications. Indeed, the physical properties of four of its radionuclides ( $^{149}$ Tb, $^{152}$ Tb, $^{155}$ Tb, $^{161}$ Tb) allow their use in each main applications of nuclear medicine. $^{149}$ Tb is the lowest mass alpha emitter with suitable physical properties for receptor-targeted alpha therapy (TAT), and the only one among the radiolanthanides. Currently $^{149}$ Tb is only produced through spallation reactions induced by high-energy proton beam coupled with mass separation to obtain suitable purity. The aim of the present work is to investigate the production of $^{149}$ Tb using commercial cyclotrons by irradiation of natural gadolinium target. New excitation functions for proton-induced nuclear reactions on natural gadolinium have been measured.

Abstract: Physics letters / B B 800, 135042 - (2020). doi:10.1016/j.physletb.2019.135042, Measurements of the cross sections for the production of single top quarks and antiquarks in the $t$ channel, and their ratio, are presented for proton-proton collisions at a center-of-mass energy of 13 TeV. The data set used was recorded in 2016 by the CMS detector at the LHC and corresponds to an integrated luminosity of 35.9 fb$^{-1}$. Events with one muon or electron are selected, and different categories of jet and b jet multiplicity and multivariate discriminators are applied to separate the signal from the background. The cross sections for the $t$-channel production of single top quarks and antiquarks are measured to be 136 $\pm$ 1 (stat) $\pm$ 22 (syst) pb and 82 $\pm$ 1 (stat) $\pm$ 14 (syst) pb, respectively, and their ratio is 1.66 $\pm$ 0.02 (stat) $\pm$ 0.05 (syst). The results are in agreement with the predictions from the standard model., Published by North-Holland Publ., Amsterdam

Abstract: In this thesis, we investigate the vibronic (de-) excitation and dissociative recombination of CH+ by low-energy electron impact. We first develop a theoretical approach for the electron-impact vibronic (de-) excitation of CH+. In this approach, the fixed-nuclear R-matrix method is employed to compute electron-ion scattering matrices in the Born-Oppenheimer approximation. A vibronic frame transformation and the closedchannel elimination procedure in a spirit of molecular quantum defect theory are employed to construct an energy-dependent scattering matrix describing interactions between vibronic channels of the target ion induced by the incident electron. The obtained scattering matrix accounts for Rydberg series of vibronic resonances in the collisional spectrum. Cross sections for vibronic excitation for different combinations of initial and final vibronic states are computed. A good agreement between electronic-excitation cross sections, obtained using the quantum defect theory and in a direct R-matrix calculation, demonstrates that the present approach provides a reliable tool for determination of vibronic (de-) excitation cross sections for targets with low-energy electronic resonances. Such targets were difficult to treat theoretically using earlier methods. Within the same framework applied for the vibronic (de-) excitations, we further compute the cross section for low-energy dissociative recombination of CH+ coupling the outgoing-wave basis function defined by complex absorbing potential. The contribution of the three lowest X 1Σ +, a 3Π and A 1Π ionic states and the Rydberg series converging to those states are taken into account. The obtained DR cross sections are quantitatively in good agreement with the experimental measurements and exhibit a resonanc feature analogous to the experimental cross-section curve. The origination of the prominant resonances in the computed results are analyzed through computing the DR probabilities for the partial waves of the incident electron. The d-type partial waves including dσ, dπ and dδ are found considerably contributing to the DR of the ground-state CH+. This may explain the discrepancies observed between thoery and experiment in the preceeding studies., Dans cette thèse, nous étudions la (dé)excitation vibronique et la recombinaison dissociative du CH+ par impact d'électrons de faible énergie. Nous développons d'abord une approche théorique de l'excitation (dé)vibronique de CH+ par impact d'électrons. Dans cette approche, la méthode de la matrice R à noyaux fixes est utilisée pour calculer les matrices de diffusion des électrons et des ions dans l'approximation de Born-Oppenheimer. Une transformation vibronique du cadre et la procédure d'élimination à canal fermé dans l'esprit de la théorie des défauts quantiques moléculaires sont utilisées pour construire une matrice de diffusion dépendant de l'énergie décrivant les interactions entre les canaux vibroniques de l'ion cible induits par l'électron incident. La matrice de diffusion obtenue tient compte de la série de résonances vibroniques de Rydberg dans le spectre de collision. Les sections transversales de l'excitation vibronique pour différentes combinaisons d'états vibroniques initiaux et finaux sont calculées. Un bon accord entre les sections transversales d'excitation électronique, obtenu en utilisant la théorie des défauts quantiques et dans un calcul direct de matrice R, démontre que l'approche actuelle fournit un outil fiable pour la détermination des sections transversales d'excitation (dé)vibronique pour des cibles avec des résonances électroniques de faible énergie. De telles cibles étaient difficiles à traiter théoriquement avec les méthodes précédentes. Dans le même cadre que celui appliqué aux excitations (dé)vibroniques, nous calculons en outre la section transversale pour la recombinaison dissociative à basse énergie de CH+ couplant la fonction de base de l'onde sortante définie par le potentiel d'absorption complexe. La contribution des trois états ioniques X 1Σ +, a 3Π et A 1Π les plus bas et la série de Rydberg convergeant vers ces états sont pris en compte. Les sections transversales DR obtenues sont quantitativement en bon accord avec les mesures expérimentales et présentent une caractéristique de résonance analogue à la courbe de la section transversale expérimentale. L'origine des résonances proéminentes dans les résultats calculés est analysée par le calcul des probabilités de DR pour les ondes partielles de l'électron incident. On constate que les ondes partielles de type d, notamment dσ, dπ et dδ, contribuent considérablement à la DR du état de terrain CH+. Cela peut expliquer les écarts observés entre la théorie et l'expérience dans les études précédentes.

Abstract: Soil erosion is a complex phenomenon, which particularly influences water and soil potentials. In the mountainous areas, water erosion phenomenon is accentuated by steep slopes and the degradation of vegetation cover. soil erosion is a worldwide phenomenon threatening the social, environmental and the economic life. In Morocco, fluvial erosion is one of the issues that affects the national territory. The location of Morocco, in the south of Mediterranean region provides remarkable climatic and ecological diversity. Located in the Moroccan High Atlas, El Abid basin belongs to a semi-arid climate. It is characterized by steep slopes and abundant precipitation which gives mountain flows a torrential characteristic. The discharge can reach very important values. Long term hydrological records for El Abid river (1970-2017) demonstrate the annual and seasonal variability in discharge with winter and spring periods typically representing 87% of the flow. Soils are increasingly degraded and sediments from erosion contribute to the siltation of Bin Ouidane dam. This siltation is the result of deposits of soil erosion. During flood periods this dam is silted by the sediment transport. This article aims to quantify the rate of fluvial erosion in the upstream section of the Bin El Ouidane dam. Then, to understand the process of river dynamics and its impact on silting issue, through the application of an approach technique based on the realization of several cross profiles, and with a main objective being to compare the results of the river dynamics of the two campaigns during 2016 and 2017. In addition, the measurements taken were supplemented by qualitative observations, particularly during the baseflow of the river, the incision of the bed (or stream), the regressive erosion of the banks, the apparent nature of the substrate, and certain anthropogenic actions.

Abstract: The traditional methodology of nuclear data evaluation, which has been in use for the past four decades, is showing its limitations in reducing significantly the uncertainties in neutron cross sections below their current level. This suggests that a new approach should be considered. This PhD work aims at demonstrating that a major qualitative improvement is possible by changing the reference frame historically used for evaluating nuclear data model. The central idea was to move from restrictive frame of the incident neutron and target nucleus to the more general frame of the excited compound system. Such a change, which implies the simultaneous modelling of all the reactions leading to the same compound system, opens up the possibility of direct comparison between nuclear model parameters, whether those are derived for reactor physics applications for reactor physicsapplications, astrophysics or basic nuclear spectroscopy studies. This have the double advantage of bringing together evaluation activities performed separately, and of pooling experimental databases and basic theoretical nuclear parameter files. During this PhD thesis, a new module, so called TORA (TOol for Reactions Analysis), was implemented within the CONRAD system of the CEA/LEPh, to allow the change of paradigm foreseen for next generation of evaluated neutron cross sections. After rigorous numerical validation of the TORA module, this work ends by associated studies within this new frame., La méthode classique d’évaluation des données nucléaires pour la Physique des réacteurs, en vigueur depuis quatre décennies, atteint maintenant ses limites en terme de réduction des incertitudes sur les sections efficaces neutroniques. Ce constat nous a conduit à définir une approche nouvelle plus exhaustive en terme de processus physiques et de types d’observables capitalisables. Le travail de thèse présenté ici a pour objectif la démonstration qu’une amélioration qualitative majeure sur les paramètres a posteriori dans l’ajustement des sections efficaces, est réalisable en changeant de référentiel de travail, passant du cadre historique du neutron incident sur un noyau cible (c’est à dire de la spectroscopie neutronique)au cadre plus universel du centre de masse du système composé excité. Un tel changement de philosophie implique la modélisation effective simultanée de toutes réactions nucléaires menant au même système composé, ouvrant par voie de conséquence une inter-comparaison immédiate entre paramètres des modèles nucléaires provenant des différents pans de la physique, qu’ils soient issus des applications en physique de réacteurs ou de problématiques d’astrophysique ou de structure de la matière. La méthode ici décrite présente l’avantage de réunir des activités d’une même thématique (l’évaluation de données), habituellement exécutées séparément et ce, en regroupant les différentes bases de données expérimentales et différents jeux de paramètres ; qu’ils soient qualifiés d’ "a priori" ou d’ "a posteriori" dans le processus d’ajustement des données. Cette procédure a été mise en œuvre au travers du développement d’un nouveau module dénommé TORA (TOol for Reactions Analysis) du code CONRAD (COde for Nuclear Reaction Analysis and Data Assimilation) du Commissariat à l’Energie Atomique et aux Energies Alternatives (CEA). Ce nouvel outil permet de calculer de façon autonome toutes sections efficaces neutroniques ou particules chargées microscopiques différentielles ou intégrées en angle qu’elles soient mesurées par rapport au référentiel des particules incidentes ou émergentes. Après une validation numérique des résultats des voies isolées de réaction par rapport aux codes institutionnalisés (CONRAD, SAMMY, NJOY, etc.) et après une comparaison des résultats TORA avec ceux d’un cas test de référence établi au niveau de la communauté scientifique des données nucléaires et traitant du système composé $^7$Be$^∗$ , l’accent a été mis sur une application concrète et d’actualité : le système composé $^{17}$O$^∗$. La problématique de la réduction des incertitudes des sections efficaces neutroniques de l’ $^{16}$O impliquant le système composé $^{17}$O$^∗$ , a été mise récemment en lumière au travers du projet international CIELO (Collaborative International Evaluation Library Organisation) qui a abouti en particulier à une clarification sur l’amplitude de la section efficace $^{16}$O(n, $\alpha$) $^{13}$C, réévaluée à la hausse de 40%. C’est le type de problème que l’approche unifiée de ce travail doit permettre à terme de prévenir en ayant un jeu unique cohérent de paramètres nucléaires (les paramètres fondamentaux de la théorie de la matrice R ; les amplitudes réduites $\gamma _c$ par voie d’excitation c d’un état du système composé) pour la reproduction des résonances observées quelle que soit la spectroscopie de réaction. En effet, historiquement les sections efficaces mesurées $^{16}$O(n, $\alpha$) $^{13}$C et $^{13}$C($\alpha$, n) $^{16}$O, ne pouvaient être l’objet d’un ajustement simultané et la mesure de la section efficace $^{13}$C($\alpha$, n) $^{16}$O devait être renversée (temporellement) pour rejoindre la base expérimentale neutronique de $^{16}$O sous la forme d’une pseudo-mesure $^{16}$O(n, $\alpha$) $^{13}$C et ainsi pouvoir compléter l’information disponible pour l’évaluation des données de $^{17}$O$^∗$ . Au-delà de cette question argumentée dans le manuscrit, une ébauche d’ajustement des sections efficaces neutroniques de $^{16}$O au travers de mesures de la base expérimentale rassemblée par le projet CIELO est réalisée avec comme produit fini des paramètres de résonance sous forme d’amplitudes réduites (et non pas sous forme de largeurs à mi-hauteur observées comme habituellement) avec rattachement à la structure nucléaire de l’ $^{17}$O, puisque étant définis par rapport à une énergie d’excitation dont l’origine de l’échelle se trouve être l’énergie de l’état fondamental de ce dernier. Une question, connexe au traitement matrice R et à l’énergie reportée dans la bibliographie pour les résonances observées, repose sur le choix de la convention choisie pour le calcul du facteur de déphasage, S$_l$, et ses implications notamment à l’ouverture énergétique (seuil) d’une réaction. Un survol de la problématique est donné dans le manuscrit.

Abstract: DOI: https://doi.org/10.1103/PhysRevA.100.032713arXiv link: http://arxiv.org/abs/1910.00657; International audience; Anion and cation emission following water dissociation was studied for 6.6-keV $^{16}$O$^{+}$ + H$_{2}$O collisions. Absolute cross sections for the emission of all positively and negatively charged fragments, differential in both energy and observation angle, were measured. The fragments formed in hard, binary collisions appearing in peaks were distinguishable from those created in soft collisions with many-body dynamics that result in a broad energy spectrum. A striking feature is that anions and cations are emitted with similar energy and angular distributions, with a nearly constant ratio of about 1:100 for H$^{-}$ to H$^{+}$. Model calculations were performed at different levels of complexity. Four-body scattering simulations reproduce the measured fragment distributions if adequate kinetic-energy release of the target is taken into account. Providing even further insight into the underlying processes, predictions of a thermodynamic model indicate that transfer ionization at small impact parameters is the dominant mechanism for H$^{+}$ creation. The present findings confirm our earlier observation that in molecular fragmentation induced by slow, singly charged ions, the charge states of the emitted hydrogen fragments follow a simple statistical distribution independent of the way they are formed.

Abstract: Summary: Charged particle therapy exploits proton or 12C beams to treat deep-seated solid tumors. Due to the advantageous characteristics of charged particles energy deposition in matter, the maximum of the dose is released to the tumor at the end of the beam range, in the Bragg peak region. However, the beam nuclear interactions with the patient tissues induces fragmentation both of projectile and target nuclei and needs to be carefully taken into account. In proton treatments, target fragmentation produces low energy, short range fragments along all the beam range, which deposit a non negligible dose in the entry channel. In 12C treatments the main concern is represented by long range fragments due to beam fragmentation that release their dose in the healthy tissues beyond the tumor. The FOOT experiment (FragmentatiOn Of Target) of INFN is designed to study these processes, in order to improve the nuclear fragmentation description in next generation Treatment Planning Systems and the treatment plans quality. Target (16O and 12C nuclei) fragmentation induced by –proton beams at therapeutic energies will be studied via an inverse kinematic approach, where 16O and 12C therapeutic beams impinge on graphite and hydrocarbon targets to provide the nuclear fragmentation cross section on hydrogen. Projectile fragmentation of 16O and 12C beams will be explored as well. The FOOT detector includes a magnetic spectrometer for the fragments momentum measurement, a plastic scintillator for ΔE and time of flight measurements and a crystal calorimeter to measure the fragments kinetic energy. These measurements will be combined in order to make an accurate fragment charge and isotopic identification.

Abstract: In Pb-Pb collisions at the LHC, a hot and dense medium of deconfined quarks and gluons is formed, the so-called Quark-Gluon Plasma (QGP). The QGP is conjectured to be the state of matter of the early Universe up to few microseconds after the Big Bang and may still exist in the core of neutron stars. One of the most striking signatures of the QGP formation in heavy-ion collisions is the suppression of jet production. This phenomenon, called jet quenching, is ascribed to the energy lost by the initial parton while traveling through the QGP medium. In the last two decades, many theoretical developments of the theory of jet quenching have been formulated within pQCD.The main energy loss mechanisms proposed in the literature are attributed to radiative and collisional processes. Another kind of energy loss is developed in this work comprises a background field induced radiative energy loss which besides that besides scattering effects. Under the suggested model, a fast parton propagating through the medium will feel the effect of the color magnetic and the color electric fields while undergoing multiple scatterings with the particles in the medium.Besides, theoretical models predict that energy loss depends on the color charge and mass of the hard-scattered parton traversing the medium. Such mass dependence can be studied by measuring the production of hadrons and jets containing heavy-quarks in pp, p-Pb and Pb-Pb collisions at the LHC.In this thesis report, a new model for the medium is presented, which is described as a collection of static colored scattering centers in the presence of a chromomagnetic field, together with the description of the related energy loss mechanism. The ALICE measurement of b-jet production in pp and p-Pb collisions at √s_ℕ=5.02 TeV using an impact parameter based tagger is also presented., Dans les collisions Pb-Pb au LHC, un milieu chaud et dense formé de quarks et de gluons déconfinés est formé, communément appelé Plasma de Quarks et de Gluons (PQG). Le PQG est l’état hypothétique de l’univers primordial quelques microsecondes après le Big Bang et constituerait encore à ce jour le cœur des étoiles à neutrons. Une des signatures les plus frappantes de l’occurrence du PQG lors de collisions d’ions lourds est la suppression des jets. Ce phénomène appelé étouffement des jets est attribué au mécanisme de perte d’énergie du parton à l’origine du jet lors de son trajet au travers du milieu formé par le PQG.Les deux dernières décennies ont vu l’émergence d’une formulation théorique du phénomène d’étouffement des jets dans le cadre de la Chromo Dynamique Quantique. La perte d’énergie étant le plus fréquemment attribuée dans la littérature à des processus radiatifs et collisionnels. Un nouveau mécanisme de perte d’énergie à été étudié dans ce travail de thèse qui outre la description des effets de diffusions multiples, met en œuvre une perte d’énergie radiative induite par un champ chromomagnétique, de sorte qu’un parton rapide se propageant au travers du milieu ressentira l’effet des champs magnétique et de couleur tout en subissant des diffusions multiples avec les particules du milieu. De plus, les modèles théoriques prédisent une dépendance de la perte d’énergie avec la charge de couleur et la masse du parton issu d’une diffusion à grand transfert d’impulsion lors de sa traversée du milieu. Une telle dépendance en masse peut être étudiée en mesurant la production de hadrons et de jets contenant des quarks lourds dans les collisions pp, p-Pb et Pb-Pb au LHC. Dans cette thèse, un modèle original du milieu est présenté, décrit comme un ensemble de centres de diffusion statiques colorés en présence d’un champ chromomagnétique, de même qu’une description du mécanisme de perte d’énergie associé. Enfin, la mesure de la production de jets issus de quarks beaux avec le détecteur ALICE dans les colllsions pp et p-Pb à l’énergie de 5.02 TeV au LHC à l’aide d’une méthode d’étiquetage utilisant le paramètre d’impact des traces est présenté dans cette thèse.

Abstract: International audience; In this review article we present some of the major applications for cosmogenic nuclide studies; extraterrestrial applications on meteorites, lunar surface samples but also on interstellar grains and terrestrial applications ranging from ages for exposure and burial over erosion and denudation rates to uplift and soil dynamics. For all the applications a good knowledge of the cosmogenic nuclide production rates is indispensable. Since it is neither possible nor feasible measuring production rates for all possible set-ups and geometries they are usually calculated using the particle spectra for primary and secondary particles and the cross sections for the relevant nuclear reactions. Considering the reacting particles we also discuss in some detail the basic properties of solar and galactic cosmic rays, especially we focus on the temporal variability. With a good understanding of the projectile types, a very relevant step is to understand and model the induced nuclear reactions. In doing so, we will briefly discuss the basic properties of spallation reactions and we especially focus on the recent very impressive improvements. We finish with a short outlook of the next possible steps for further improvements.

Abstract: Several experiments takes to the task of measuring the parameters of the standard modelrelated to the neutrinos. For instance, the JUNO experiment in China has for aim to decideon the mass hierarchy of the three states responsible of the propagation of the neutrinos.The ”Tokai To Kamioka” (T2K) experiment is the first of many experiments that wasable to perform the first measurement on the angle of the PMNS matrix, the matrix respon-sible for the neutrino oscillation. Other experiments such as Double Chooz and Daya Bayhave also performed similar measurement on the PMNS matrix angles. The future Hyper-Kamiokandeexperiment has its sight set on the measurement of the CP factor in the PMNSmatrix, which rules for the matter/antimatter asymetry.As all the beam based oscillation experiments, The T2K measurements depend on aset of detectors near the beam production site and on a detector far away, namely Super-Kamiokande. Detecting the neutrino fluxes at the near location and at the further locationneeds a knowledge on the neutrino cross-sections with the target materials of the different de-tectors. However the near and far detectors are very different in nature. The target materialfor Super-Kamiokande is water while the one for the majority of the current near detectorsis plastic. Moreover, while we have a 4π acceptance for Super Kamiokande, we merely coverthe forward angular region with the near detectors. Because of our limited precision on thedifferent cross-sections coupled with the different materials used in the whole experiment, wehave irreductible uncertainties on the measurement of the angles.In order to improve these numbers, we must either have a better precision on the cross-section measurement with similar angular region, or we must have a measurement on theratio of the cross-sections on the two materials used in the respective detectors.The WAGASCI experiment has for goal to improve the measurements on the cross-sectionof water and plastic as well as perform a measurement on the ratio of both these cross-sections.The WAGASCI detector in its final configuration will allow the measurement of high angletracks thanks to the presence of a grid and of Side Muon Range Detectors. The detectorhas water targets as well as plastic targets, which allows to measure the ratio of the twocross-sections with the same flux. The flux being the main source of systematics errors, thatallows to improve the precision of our measurement compared to a situation where we wouldtake some data with only a water target and then only with a plastic target (this setup hasbeen used previously).In this thesis, we will go over the construction of one of the detector modules : the watermodule. We will also discuss its calibration. Finally we will expand on the analysis de-velopped to treat the data collected by the detector as well as the cross-section extractionand the systematic error estimations. The configuration used here is not the final one, wecannot yet work with high-angle events because we the side-MRD were not yet present atthe time when the data was taken. Furthermore the muon detector used could not stophigh-momentum muons because of a limited depth. However this will be enough to conducta comprehensive analysis with sufficient statistics., [Pas de résumé fourni en français]

Abstract: To attain target precisions in reactor simulation, accurate nuclear data are needed, especially for future reactors. In this work, a thorough study of (n,xn) reactions on 232Th has been realised using prompt gamma spectroscopy associated with time of flight method. Cross sections of 81 (n,n'γ), 11 (n,2nγ) and 7 (n,3nγ) have been obtained for energies from 0,2 to 20 MeV, thus expanding considerably the energy range covered by experimental data. Moreover, the influence of cross sections’ uncertainties on nuclear system simulation has been studied for thorium fuel cycle isotopes 232Th and 233U using MCNP and SERPENT codes. This work has shown that uncertainty on inelastic scattering (n,n’) for 232Th is the main contributors to uncertainty of several reactor parameters., Pour atteindre les objectifs de précision des simulations de réacteurs, des données nucléaires précises sont nécessaires, particulièrement pour les futurs réacteurs. Dans ce travail de thèse, une étude approfondie des réactions (n,xn) sur le 232Th a été réalisée par la méthode de la spectroscopie gamma prompte associée a la technique du temps de vol. Les sections efficaces de 81 (n,n'γ), 11(n,2nγ) et 7 (n,3nγ) ont été obtenues pour des énergies de 0,2 a 20 MeV, ce qui étend considérablement la gamme d’énergie couverte par les données expérimentales. De plus, l'impact de l’incertitude des sections efficaces sur la simulation de systèmes nucléaires a été examiné pour les isotopes du cycle du thorium 232Th et 233U en utilisant les logiciels MCNP et SERPENT. Ce travail a montré que l’incertitude sur la section efficace de diffusion inélastique (n,n’) du 232Th est la source d’incertitude principale pour plusieurs paramètres de réacteur.

Abstract: The analysis of fission events following the implantation of evaporation residues produced in the fusion reaction of 50Ti and 209Bi at different bombarding energies has revealed 5 millisecond decays, which are attributed to the spontaneous fission of proton-evaporation channels. The average cross sections for proton evaporation are found to be ∼100 and 10 times smaller than the largest neutron-evaporation channel cross section at the same excitation energy. These results suggest that the proton evaporation channel, albeit weak, may represent a realistic alternative to synthesize new, more neutron rich super heavy nuclei.

Abstract: AMS-02 on the International Space Station has been releasing data of unprecedented accuracy. This poses new challenges for their interpretation. We refine the methodology to get a statistically sound determination of the cosmic-ray propagation parameters. We inspect the numerical precision of the model calculation, nuclear cross-section uncertainties, and energy correlations in data systematic errors. We used the 1D diffusion model in USINE. Our $\chi^2$ analysis includes a covariance matrix of errors for AMS-02 systematics and nuisance parameters to account for cross-section uncertainties. Mock data were used to validate some of our choices. We show that any mis-modelling of nuclear cross-section values or the energy correlation length of the covariance matrix of errors biases the analysis. It also makes good models ($\chi^2_{\rm min}/{\rm dof}\approx1$) appear as excluded ($\chi^2_{\rm min}/{\rm dof}\gg1$). We provide a framework to mitigate these effects (AMS-02 data are interpreted in a companion paper). New production cross-section data and the publication by the AMS-02 collaboration of a covariance matrix of errors for each data set would be an important step towards an unbiased view of cosmic-ray propagation in the Galaxy., Comment: 24 pages, 23 figures, 3 tables: affiliations corrected

Abstract: Safety analysis and design of nuclear systems rely on accurate computer simulation tools. These simulation tools take in basic nuclear data as an input to estimate the safety parameters of the nuclear systems and ensure its normal operation. In particular, precise knowledge of light water neutron scattering cross section data is important as light water is the most widely used moderator in thermal nuclear reactors, such as pressurized water reactors (PWRs). Since PWRs operate at temperature around 550 K and pressure around 150 bar, proper understanding of light water thermal cross section data at high temperatures and pressures is necessary.In the thermal neutron energy region, the cross sections are governed by the structure and dynamics of the scattering material described by thermal scattering law (TSL). The TSL data for light water at several temperatures are available in the standard thermal scattering libraries. No information about the impact of pressure on the TSL data exists in these libraries. Until recently, the standard TSL data libraries for light water have relied mostly on physics model and experimental data measured in the 60s. One observes some discrepancies in these evaluations both at room temperature and reactor operating temperature (550 K). Experimental TSL, for high temperature and pressure, are very scarce. There is thus a need for reviewing the existing TSL evaluations and consequently performing new experiments, to develop new evaluations valid for a large range of temperature and pressure conditions of light water.The research developed during this work, deals with the measurement and evaluation of TSL data for light water at high temperatures and pressures. To generate new TSL for light water, inelastic neutron scattering measurements were carried out at two time-of-flight (TOF) spectrometers, namely the IN4c and IN6, at the Institut Laue-Langevin (ILL), Grenoble, France. A corresponding set of molecular dynamics (MD) simulations were performed to complement the experimental data using two classical interaction models for water namely, a flexible non-polarizable TIP4P/2005f and a rigid polarizable TCPE model. Frequency spectra obtained from both TOF experiment and MD simulations at different temperatures and pressures have been analyzed and new TSL evaluations for light water have been developed.A new module named as SAB module was developed in the existing IRSN nuclear data processing code, GAIA, with capabilities to generate TSL libraries for light water at the desired temperature requested by the user. The SAB module was validated on the French plutonium temperature effect experimental program, where TSL evaluations at exact temperatures of the experiment were necessary to observe a positive temperature effect.The performance of the newly developed TSL evaluations, i.e. S(α β)JEFF-3.3-MOD, S(α β)ILL and S(α β)TCPE were tested on a series of differential, double differential and total cross section measurements available inthe literature. For further verification and validation of the new TSL data, critical benchmarks available in theInternational Handbook of Evaluated Criticality Safety Benchmark Experiments (ICSBEP Handbook), sensitive to TSL have been used. In addition, the new IRSN 16O and 235U evaluations along with 235U Prompt Fission Neutron Spectrum (PFNS) from ENDF/B-VIII.0 were tested in conjunction with the new TSL evaluations.The outcome of this study leads to a better interpretation of the impact of temperature and pressure on TSL in PWR applications. It is suggested that a similar study for nuclear reactors operating with different moderators (for instance heavy water, graphite, etc.,) should be conducted to investigate whether a similar behavior like the one observed in light water is seen.; Les études de sûreté et la conception de nouveaux systèmes nucléaires nécessitent d’avoir recours à des outils de simulation efficaces. Ceux-ci dépendent des données nucléaires de base qui leur sont fournies, afin d’estimer au mieux les critères de sûreté des systèmes nucléaires et d’assurer leur bon fonctionnement. En particulier, une bonne connaissance des sections efficaces de l’eau légère est importante, car l’eau est le modérateur le plus employé dans les réacteurs nucléaires thermiques, comme les réacteurs à eau pressurisée (REP). Ces derniers fonctionnent à des températures et des pressions avoisinant 550 K et 150 bar, ce qui implique de connaître les sections efficaces de l’eau dans ces conditions.Les sections efficaces neutroniques dans le domaine d’énergie thermique dépendent de la structure et de la dynamique du matériau diffusant, décrites par des lois de diffusion thermiques (thermal scattering law, TSL). Les TSL de l’eau légère sont consignées pour plusieurs températures dans des bibliothèques standard de diffusion thermique. Jusqu’à récemment, ces bibliothèques reposaient essentiellement sur des modèles physiques etdes mesures expérimentales réalisées dans les années soixante, et des écarts peuvent être constatés dans ces évaluations à température ambiante et à la température de fonctionnement d’un réacteur (550K). Non seulement, les données expérimentales pour les TSL à hautes pressions et hautes températures sont rares, mais aucune information n’est disponible quant à l’impact de la pression sur les TSL. Par conséquent, il existe un réel besoin de revoir les évaluations des TSL existantes, et ainsi de proposer de nouvelles expériences, pour obtenir des bibliothèques indépendantes des modèles physiques et valides sur une large gamme de températures et de pressions.Ce travail de recherche porte sur la mesure et l’évaluation de la loi de diffusion thermique de l’eau légère à hautes températures et hautes pressions. Pour produire de nouvelles TSL, des mesures de la diffusion inélastique des neutrons sur l’eau ont été effectuées à l’Institut Laue-Langevin (ILL) à Grenoble, à l’aide de deux spectromètres à temps de vol (TOF), IN4c et IN6. Afin de compléter ces mesures, des simulations de dynamique moléculaire (MD) ont été réalisées en s’appuyant sur deux modèles classiques d’interaction moléculaire, le modèle non polarisable TIP4P/2005f (utilisé dans le code GROMACS) et le modèle polarisable TCPE (utilisé dans le code PolarisMD). Les spectres de fréquence à différentes pressions et températures obtenus grâce aux mesures de temps de vol et aux simulations MD ont été exploités pour développer de nouvelles TSL pour l’eau légère.Un nouveau module nommé SAB a été développé dans l’actuel code de traitement des données nucléaires de l’IRSN, GAIA, capable de produire des bibliothèques de diffusion thermique pour l’eau légère aux températures requises par l’utilisateur. Le module SAB a été validé sur le programme expérimental français d’étude de l’effet de la température sur le plutonium : afin d’observer une évolution positive de la réactivité avec la température,des bibliothèques de diffusion thermique aux températures exactes ont été nécessaires.Les performances de ces nouvelles bibliothèques, i.e. S(α β)JEFF-3.3-MOD, S(α β)ILL and S(α β)TCPE ont été testées sur une série de mesures de sections efficaces différentielles, double-différentielles et totales disponibles dans la littérature. Des benchmarks critiques de l’International Handbook of Evaluated Criticality Safety Benchmark Experiments (ICSBEP Handbook) ont également été utilisés. Enfin, les évaluations du 16O et du 235U de l’IRSN, ainsi que l’évaluation du 235U PFNS de la bibliothèque ENDF/B-VIII.0 ont été utilisées conjuguées aux nouvelles TSL produites.Les résultats de ces études permettent une meilleure compréhension de l’impact de la température et de la pression sur les TSL dans les applications liées à l’exploitation des REP. Il est suggéré qu’un travail comparable soit conduit pour les réacteurs nucléaires utilisant d’autres modérateurs que l’eau légère (eau lourde, graphite, etc.,), afin de savoir si des comportements similaires sont observés.

Abstract: 233U is of key importance among the fissile nuclei in the Th-U fuel cycle. A particularity of 233U is its small neutron capture cross-section, which is on average about one order of magnitude lower than the fission cross-section. The accuracy in the measurement of the 233U capture cross-section depends crucially on an efficient capture-fission discrimination, thus a combined set-up of fission and γ-detectors is needed. A measurement of the 233U capture cross-section and capture-to-fission ratio was performed at the CERN n_TOF facility. The Total Absorption Calorimeter (TAC) of n_TOF was employed as γ-detector coupled with a novel compact ionization chamber as fission detector. A brief description of the experimental set-up will be given, and essential parts of the analysis procedure as well as the preliminary response of the set-up to capture are presented and discussed.

Abstract: The 12C+ 12C fusion reaction plays a key role in the late evolution of massive stars. Its cross section exhibits strong resonances down to the astrophysical region of interest, often associated with a molecular configuration of the 24Mg nucleus. In this thesis, the 12C+ 12C fusion cross section has been measured from the Coulomb barrier down to the astrophysical region of interest. The charged particle-gamma coincidence technique has been used. A new experimental setup, STELLA, has been developed and built during this thesis. It is composed of a reaction chamber, a set of annular silicon strip detectors, a rotating target mechanism, an ultra high vacuum system, a digital time-stamped data acquistion system, and a structure that fits 36 LaBr3 detectors. STELLA has been installed at the Andromède facility (Orsay, France). Successfull experiments have been carried out to extract fusion cross sections down to the Gamow window for the carbon burning phase of massive stars.; La réaction de fusion 12C+ 12C marque un tournant dans l’évolution des étoiles massives.

La mesure en coïncidence des particules chargées et des γ a été employée. Un dispositif expérimental, STELLA, a été développé et construit au cours de cette thèse. Il comprend une chambre à réaction, des détecteurs annulaires au silicium, un mécanisme de cibles tournantes, un système de pompage pour vide poussé, un système d’acquisition digital, et une structure pour supporter 36 détecteurs LaBr3.

Abstract: Neutron capture cross section measurements on$^{155}$Gd and$^{157}$Gd were performed using the time-of-flight technique at the n_TOF facility at CERN on isotopically enriched samples. The measurements were carried out in the n_TOF experimental area EAR1, at 185 m from the neutron source, with an array of 4 C$_{6}$D$_{6}$ liquid scintillation detectors. At a neutron kinetic energy of 0.0253 eV, capture cross sections of 62.2(2.2) and 239.8(8.4) kilobarn have been derived for$^{155}$Gd and$^{157}$Gd, respectively, with up to 6% deviation relative to values presently reported in nuclear data libraries, but consistent with those values within 1.6 standard deviations. A resonance shape analysis has been performed in the resolved resonance region up to 181 eV and 307 eV, respectively for$^{155}$Gd and$^{157}$Gd, where on average, resonance parameters have been found in good agreement with evaluations. Above these energies and up to 1 keV, the observed resonance-like structure of the cross section has been analysed and characterised. From a statistical analysis of the observed neutron resonances we deduced: neutron strength function of $2.01(28) \times 10^{-4}$ and $2.17(41) \times 10^{-4}$ , average total radiative width of 106.8(14) meV and 101.1(20) meV and s-wave resonance spacing 1.6(2) eV and 4.8(5) eV for n +$^{155}$Gd and n +$^{157}$Gd systems, respectively. Neutron capture cross section measurements on$^{155}$Gd and$^{157}$Gd were performed using the time-of-flight technique at the n_TOF facility at CERN on isotopically enriched samples.

Neutron capture measurements on $^{155}$Gd and $^{157}$Gd were performed using the time-of-flight technique at the n\_TOF facility at CERN. Four samples in form of self-sustaining metallic discs isotopically enriched in $^{155}$Gd and $^{157}$Gd were used. The measurements were carried out at the experimental area (EAR1) at 185 m from the neutron source, with an array of 4 C$_6$D$_6$ liquid scintillation detectors. The capture cross sections of $^{155}$Gd and $^{157}$Gd at neutron kinetic energy of 0.0253 eV have been estimated to be 62.2(2.2) kb and 239.8(9.3) kb, respectively, thus up to 6\% different relative to the ones reported in the nuclear data libraries. A resonance shape analysis has been performed in the resolved resonance region up to 180 eV and 300 eV, respectively, in average resonance parameters have been found in good agreement with evaluations. Above these energies the observed resonance-like structures in the cross section have been tentatively characterised in terms of resonance energy and area up to 1 keV.

Abstract: A measurement is presented of the associated production of a single top quark and a Z boson. The study uses data from proton-proton collisions at $\sqrt{s} =$ 13 TeV recorded by the CMS experiment, corresponding to an integrated luminosity of 35.9 fb$^{-1}$. Using final states with three leptons (electrons or muons), the tZq production cross section is measured to be $\sigma$(pp$\to$tZq$\to$Wb$\ell^+\ell^-$q) = $123 ^{+33}_{-31}$ (stat) $^{+29}_{-23}$ (syst) fb, where $\ell$ stands for electrons, muons, or $\tau$ leptons, with observed and expected significances of 3.7 and 3.1 standard deviations, respectively., Comment: Replaced with the published version. Added the journal reference and the DOI. All the figures and tables can be found at http://cms-results.web.cern.ch/cms-results/public-results/publications/TOP-16-020 (CMS Public Pages)

Abstract: Following the completion of the second neutron beam line and the related experimental area (EAR2) at the n_TOF spallation neutron source at CERN, several experiments were planned and performed. The high instantaneous neutron flux available in EAR2 allows to investigate neutron indiced reactions with charged particles in the exit channel even employing targets made out of small amounts of short-lived radioactive isotopes. After the successful measurement of the 7Be(n,{\alpha}){\alpha} cross section, the 7Be(n,p)7Li reaction was studied in order to provide still missing cross section data of relevance for Big Bang Nucleosynthesis (BBN), in an attempt to find a solution to the cosmological Lithium abundance problem. This paper describes the experimental setup employed in such a measurement and its characterization., The authors are grateful to Carmelo Marchetta (INFN-LNS) for the production of the 6LiF test target.

Abstract: The Milky Way dark matter halo is formed from the accretion of smaller subhalos. These sub-units also harbor stars---typically old and metal-poor---that are deposited in the Galactic inner regions by disruption events. In this Letter, we show that the dark matter and metal-poor stars in the Solar neighborhood share similar kinematics due to their common origin. Using the high-resolution Eris simulation, which traces the evolution of both the dark matter and baryons in a realistic Milky-Way analog galaxy, we demonstrate that metal-poor stars are indeed effective tracers for the local, virialized dark matter velocity distribution. The local dark matter velocities can therefore be inferred from observations of the stellar halo made by the Sloan Digital Sky Survey within 4 kpc of the Sun. This empirical distribution differs from the Standard Halo Model in important ways and suggests that the bounds on the spin-independent scattering cross section may be weakened for dark matter masses below $\sim$10 GeV. Data from Gaia will allow us to further refine the expected distribution for the smooth dark matter component, and to test for the presence of local substructure., Comment: 6 pages, 3 figures + supplementary material; v2: Fig. 3 updated, minor text revisions, overall conclusions unchanged (journal version)

Abstract: The study of (a,g) reactions of astrophysical interest is quite vast. These reactions play an important role in the quiescent Helium burning phase of stars, in big bang nucleosynthesis and in most explosive stellar scenarios. The studies of (a,g) reactions involving stable beams are performed in various ways. I have been concentrating on two of them. The first one is studying these reactions in direct kinematics by detecting the produced gamma rays. This is what I did during my thesis to measure the cross section of 7Li(a,g)11B. It has been studied throughout the years for several purposes in nuclear astrophysics. For example, it was postulated it could solve the big bang nucleosynthesis Lithium problem. Nowadays, it is clear it does not.However, this reaction plays a role in the production of Boron during type Ic Supernovae. Another way to study (a,g) reactions is to use inverse kinematics. The idea is to send a heavy element beam on a Helium target. This kind of kinematics allows for the detection, with good efficiency, of the heavy recoil product if the beam that did not interact in the target is properly separated. Recoil mass separators, like St. George, are built for this purpose. St. George will be involved in measuring cross sections of reaction important for the s-process like 16O(a,g)20Ne., L’étude des réaction (a,g) d’intérêt astrophysique est vaste. Ces réactions ont un rôle important dans la phase de fusion d’hélium des étoiles, dans la nucléosynthèse au moment du big bang ainsi que dans une grande partie des scénarios d'explosions stellaires. L’étude des réactions (a,g) impliquant des faisceaux stables peut être réalisée de diverse façon. Je me suis concentrée sur deux d'entre elles. La première est l’étude en cinématique directe en détectant les rayons gamma produits. C'est ce que j'ai fait durant ma thèse pour mesurer la section efficace de 7Li(a,g)11B. Cette réaction a été étudiée au cours des années pour différentes raisons en astrophysique nucléaire. Par exemple, il a été postule que cette réaction pourrait résoudre, au moment de la nucléosynthèse du big bang, le problème du Lithium. Il est clair, aujourd'hui, que ce n'est pas la solution, cependant, elle a un rôle dans la production de boron lors des supernovae de type Ic. Une autre façon d’étudier les réactions (a,g) est d'utiliser la cinématique inverse. L’idée est d'envoyer un faisceau d'ions lourd sur une cible d’hélium. Ce type de cinématique permet de détecter, avec une bonne efficacité, le noyau lourd de recul produit si le faisceau qui n'a pas interagit avec la cible, en est correctement séparé. Les séparateurs de masses, comme St. George, sont construit dans ce but. St. George sera impliquer dans la mesure de sections efficaces de réaction d’importance pour le processus s comme 16O(a,g)20Ne.

Abstract: The 12C+ 12C fusion reaction plays a key role in the late evolution of massive stars. Its cross section exhibits strong resonances down to the astrophysical region of interest, often associated with a molecular configuration of the 24Mg nucleus. In this thesis, the 12C+ 12C fusion cross section has been measured from the Coulomb barrier down to the astrophysical region of interest. The charged particle-gamma coincidence technique has been used. A new experimental setup, STELLA, has been developed and built during this thesis. It is composed of a reaction chamber, a set of annular silicon strip detectors, a rotating target mechanism, an ultra high vacuum system, a digital time-stamped data acquistion system, and a structure that fits 36 LaBr3 detectors. STELLA has been installed at the Andromède facility (Orsay, France). Successfull experiments have been carried out to extract fusion cross sections down to the Gamow window for the carbon burning phase of massive stars., La réaction de fusion 12C+ 12C marque un tournant dans l’évolution des étoiles massives. La section efficace présente des résonances jusqu’aux énergies d’intérêt astrophysique, généralement associées à une structure moléculaire dans le 24Mg. Au cours de cette thèse, la section efficace de fusion 12C+ 12C a été mesurée depuis la barrière de Coulomb jusqu’aux énergies d’intérêt astrophysique. La mesure en coïncidence des particules chargées et des γ a été employée. Un dispositif expérimental, STELLA, a été développé et construit au cours de cette thèse. Il comprend une chambre à réaction, des détecteurs annulaires au silicium, un mécanisme de cibles tournantes, un système de pompage pour vide poussé, un système d’acquisition digital, et une structure pour supporter 36 détecteurs LaBr3. STELLA a été installée auprès de l’accélérateur Andromède (Orsay, France) et une série d’expériences fructueuses ont permis d’obtenir des résultats cohérents au cœur de la fenêtre de Gamow pour la phase de combustion du carbone dans les étoiles massives.

Abstract: International audience; Self-shielding due to the resonance of cross sections influences the neutron spectrum. Mature treatment of the self-shielding has been developed in deterministic neutron transport codes. However, the correction of both neutron flux and cross sections cannot ensure the accuracy of calculated Displacement per Atom (DPA), which depends not only on cross sections, but also the corresponding recoil energies of the Primary Knocked-on Atom (PKA). The present study focuses on 56Fe because it is the most abundant isotope in the stainless steel, which is the material for the reactor pressure vessel in light water reactors and that of the fuel cladding in fast reactors. Due to the temperature dependence of cross sections, the temperature effect is firstly analyzed. Results show that the Doppler effect has small influence on DPA calculation for 56Fe. 33-group and 1968-group DPA cross sections are then used to investigate the influence of the self-shielding on the DPA calculation. The effect of the self-shielding on DPA rate calculation is examined in the fuel cladding in the ASTRID inner core. The contribution of the elastic scattering, inelastic scattering, and disappearance reactions to total DPA are 82.7percent, 17.1percent, and 0.1percent, respectively. Relative and respective reductions are 11.3percent, 5.9percent, and 20.5percent by taking the self-shielding into account. The calculation of DPA is not summable after self-shielding correction because the DPA calculated by total cross sections is 2.3percent lower the sum of the above three components.

Abstract: Monte Carlo (MC) neutron transport simulations are widely used in the nuclear community to perform reference calculations with minimal approximations. The conventional MC method has a slow convergence according to the law of large numbers, which makes simulations computationally expensive. Cross section computation has been identified as the major performance bottleneck for MC neutron code. Typically, cross section data are precalculated and stored into memory before simulations for each nuclide, thus during the simulation, only table lookups are required to retrieve data from memory and the compute cost is trivial. We implemented and optimized a large collection of lookup algorithms in order to accelerate this data retrieving process. Results show that significant speedup can be achieved over the conventional binary search on both CPU and MIC in unit tests other than real case simulations. Using vectorization instructions has been proved effective on many-core architecture due to its 512-bit vector units; on CPU this improvement is limited by a smaller register size. Further optimization like memory reduction turns out to be very important since it largely improves computing performance. As can be imagined, all proposals of energy lookup are totally memory-bound where computing units does little things but only waiting for data. In another word, computing capability of modern architectures are largely wasted. Another major issue of energy lookup is that the memory requirement is huge: cross section data in one temperature for up to 400 nuclides involved in a real case simulation requires nearly 1 GB memory space, which makes simulations with several thousand temperatures infeasible to carry out with current computer systems.In order to solve the problem relevant to energy lookup, we begin to investigate another on-the-fly cross section proposal called reconstruction. The basic idea behind the reconstruction, is to do the Doppler broadening (performing a convolution integral) computation of cross sections on-the-fly, each time a cross section is needed, with a formulation close to standard neutron cross section libraries, and based on the same amount of data. The reconstruction converts the problem from memory-bound to compute-bound: only several variables for each resonance are required instead of the conventional pointwise table covering the entire resolved resonance region. Though memory space is largely reduced, this method is really time-consuming. After a series of optimizations, results show that the reconstruction kernel benefits well from vectorization and can achieve 1806 GFLOPS (single precision) on a Knights Landing 7250, which represents 67% of its effective peak performance. Even if optimization efforts on reconstruction significantly improve the FLOP usage, this on-the-fly calculation is still slower than the conventional lookup method. Under this situation, we begin to port the code on GPGPU to exploit potential higher performance as well as higher FLOP usage. On the other hand, another evaluation has been planned to compare lookup and reconstruction in terms of power consumption: with the help of hardware and software energy measurement support, we expect to find a compromising solution between performance and energy consumption in order to face the "power wall" challenge along with hardware evolution.; L’accès aux données de base, que sont les sections efficaces, constitue le principal goulot d’étranglement aux performances dans la résolution des équations du transport neutronique par méthode Monte Carlo (MC). Ces sections efficaces caractérisent les probabilités de collisions des neutrons avec les nucléides qui composent le matériau traversé. Elles sont propres à chaque nucléide et dépendent de l’énergie du neutron incident et de la température du matériau. Les codes de référence en MC chargent ces données en mémoire à l’ensemble des températures intervenant dans le système et utilisent un algorithme de recherche binaire dans les tables stockant les sections. Sur les architectures many-coeurs (typiquement Intel MIC), ces méthodes sont dramatiquement inefficaces du fait des accès aléatoires à la mémoire qui ne permettent pas de profiter des différents niveaux de cache mémoire et du manque de vectorisation de ces algorithmes.Tout le travail de la thèse a consisté, dans une première partie, à trouver des alternatives à cet algorithme de base en proposant le meilleur compromis performances/occupation mémoire qui tire parti des spécificités du MIC (multithreading et vectorisation). Dans un deuxième temps, nous sommes partis sur une approche radicalement opposée, approche dans laquelle les données ne sont pas stockées en mémoire, mais calculées à la volée. Toute une série d’optimisations de l’algorithme, des structures de données, vectorisation, déroulement de boucles et influence de la précision de représentation des données, ont permis d’obtenir des gains considérables par rapport à l’implémentation initiale.En fin de compte, une comparaison a été effectué entre les deux approches (données en mémoire et données calculées à la volée) pour finalement proposer le meilleur compromis en termes de performance/occupation mémoire. Au-delà de l'application ciblée (le transport MC), le travail réalisé est également une étude qui peut se généraliser sur la façon de transformer un problème initialement limité par la latence mémoire (« memory latency bound ») en un problème qui sature le processeur (« CPU-bound ») et permet de tirer parti des architectures many-coeurs.

Abstract: The slow neutron capture process (s-process) is responsible for producing about half of the elemental abundances heavier than iron in the universe. Neutron capture cross sections on stable isotopes are a key nuclear physics input for s-process studies. The 72Ge(n, γ) cross section has an important influence on production of isotopes between Ge and Zr during s-process in massive stars and therefore experimental data are urgently required. 72Ge(n, γ) was measured at the neutron time-of-flight facility n_TOF (CERN) for the first time at stellar energies. The measurement was performed using an enriched 72GeO2 sample at a flight path of 185m with a set of liquid scintillation detectors (C6D6). The motivation, experiment and current status of the data analysis are reported.

Abstract: International audience; A careful comparison of experiment and theory is important both for basic research and systematic engineering design of Thulium fiber amplifiers operating in the 2 µm region for applications such as LIDAR or spectroscopy (e.g. CO2 atmospheric absorption at 2051.4 nm). In this paper we report the design and performance of a multistage high-power PM Tm-doped fiber amplifier, cladding pumped at 793 nm. The design is the result of a careful comparison of numerical simulation, based on a three level model including ion-ion interactions, and experiment. Our simulation model is based on precise measurements of the cross sections and other parameters for both 6 and 10 µm core diameter fibers. Good agreement for several single and multistage amplifier topologies and operating conditions will be presented. Origins of the difference between theory and experiment are discussed, with emphasis on the accuracy of the cross sections and the cross relaxation parameters. Finally based on our simulation tool, we will demonstrate a design with an output power greater than 10 W for a multistage amplifier with a single-frequency signal at 2050 nm. The power stage was constructed with a 6 µm active fiber showing a 64 % optical slope efficiency. The output power is found to be within 5 % of the simulated results and is limited only by the available launched pump power of ~24 W. No stimulated Brillouin scattering is observed at the highest output power level for an active fiber well thermalized.

Abstract: International audience; Pile oscillator techniques are powerful methods to measure small reactivity worth of isotopes of interest for nuclear data improvement. The principle is to create, in a well-known neutron flux, a weak and localized perturbation, the characteristics of which (level, spectrum) can be connected to physical parameters of the source (i.e. cross sections). Techniques are called open loop if the reactor power is free to drift. On the contrary, it is called closed loop if a power control system is activated. Such pile oscillator experiments have long been held in the Minerve reactor, operated by CEA at Cadarache. A closed loop reactivity oscillator method is implemented which is based on measuring the global reactivity perturbation associated to samples motion in the core center. The technique has recently been extended by introducing CEA-made miniature fission chambers close to the irradiation channel in order to measure local perturbations of the neutron flux. New detectors and associated acquisition systems were developed by CEA for that purpose. A measurement campaign, called MAESTRO-SL, took place in 2015 in Minerve. Its objective was to assess the feasibility of the method and investigate the possibility to disentangle global and local perturbation. Main experimental results are presented and discussed in this paper, which focus on comparing data processing methods of open vs closed loop setups.First, it is demonstrated that the open loop is equivalent to the closed loop setup. Uncertainty management and methods reproducibility are discussed. Second, results show that measuring local flux depression around the oscillated sample provides indeed valuable information regarding neutron cross sections. The technique is found to be very sensitivity to the capture cross section at the expense of scattering, making it very useful to measure small capture effects of highly scattering samples.

Abstract: International audience; The detection of galactic supernova (SN) neutrinos represents one of the future frontiers of low energy neutrino physics and astrophysics. The neutron coherence of neutral currents (NCs) allows quite large cross-sections in the case of neutron rich targets, which can be exploited in detecting earth and sky neutrinos by measuring nuclear recoils. They are relatively cheap and easy to maintain. These (NC) cross-sections are not dependent on flavor conversions and, thus, their measurement will provide useful information about the neutrino source. In particular, they will yield information about the primary neutrino fluxes and perhaps about the spectrum after flavor conversions in neutrino sphere. They might also provide some clues about the neutrino mass hierarchy. The advantages of large gaseous low threshold and high resolution time projection counters (TPC) detectors are discussed.

Abstract: International audience; The aim of this work is to provide a precise and accurate measurement of the U238(n,γ) reaction cross section in the energy region from 1 eV to 700 keV. This reaction is of fundamental importance for the design calculations of nuclear reactors, governing the behavior of the reactor core. In particular, fast reactors, which are experiencing a growing interest for their ability to burn radioactive waste, operate in the high energy region of the neutron spectrum. In this energy region most recent evaluations disagree due to inconsistencies in the existing measurements of up to 15%. In addition, the assessment of nuclear data uncertainty performed for innovative reactor systems shows that the uncertainty in the radiative capture cross section of U238 should be further reduced to 1–3% in the energy region from 20 eV to 25 keV. To this purpose, addressed by the Nuclear Energy Agency as a priority nuclear data need, complementary experiments, one at the GELINA and two at the n_TOF facility, were proposed and carried out within the 7th Framework Project ANDES of the European Commission. The results of one of these U238(n,γ) measurements performed at the n_TOF CERN facility are presented in this work. The γ-ray cascade following the radiative neutron capture has been detected exploiting a setup of two C6D6 liquid scintillators. Resonance parameters obtained from this work are on average in excellent agreement with the ones reported in evaluated libraries. In the unresolved resonance region, this work yields a cross section in agreement with evaluated libraries up to 80 keV, while for higher energies our results are significantly higher.

Abstract: International audience; Instead of using encapsulated sensitive volumes to simulate charge collection during single event upset (SEU) mechanism, we use continuous variation of the charge collection in the device. Basically, the collection efficiency is equal to 1 in the core of the sensitive volume and decreases outside. Assuming that the collection efficiency decreases as a power law of the distance, we analytically find that heavy ion SEU cross-section follows a power law of the linear energy transfer (LET). Results are in agreement with a set of various experimental data from 250nm to 28nm. We also show that experimental results allow extracting technological parameters of the sensitive volume as well as the threshold LET, which is a feature of the device.

Abstract: International audience; The DarkSide project at Laboratori Nazionali del Gran Sasso (LNGS) is a dark matter direct search experiment based on the detection of rare nuclear recoils possibly induced by hypothetical dark matter particles, which are supposed to be neutral, massive (> 10 GeV) and weakly interacting (WIMP). DarkSide aims to perform background-free WIMP searches using a series of dual-phase liquid argon time projection chambers filled with ultra-pure liquid argon. The detector currently operating at LNGS is DarkSide-50, a detector which holds 46 kg of active liquid argon and is now filled with argon extracted from underground and taking data in its final configuration. Combining the underground argon data with the preceding search made with atmospheric argon, a 90% C.L. upper limit on the WIMP-nucleon spin-independent cross section of 2.0×10−44 cm2 is set. The next phase of the experiment foresees the construction of a new detector with an active mass of ∼ 20 and equipped with silicon photomultipliers, called DarkSide-20k.

Abstract: Transport properties at high temperature in gases and/or in plasmas are of very importance in various fields, namely in the field of breaking technology in arc, cutting plasma, welding or burning. Knowledge of transport coefficients is necessary for any modeling involving hydrodynamic equations. As part of the kinetic theory of diluted gas, an approximate solution of the integro-differential Boltzmann equation governing distribution functions was proposed by Chapman-Enskog. Transport coefficients are classically computed using the method of Chapman-Enskog through the collision integrals. In our study we have developed, initially, a numerical code to obtain these collision integral taking into account the singularities that may occur in the calculation of the cross sections relating to interactions between particles forming the gas and/or plasmas. Secondly, we have studied the influence of the choice of parameters of interaction potentials on transport coefficients. Subsequently, we have used the numerical code developed for evaluating and helium plasma transport coefficients by studying the influence of the choice of method for calculating chemical composition on these coefficients. Finally, a simplified model of an interaction between an electromagnetic wave and a helium plasma has been proposed as a direct application of the transport coefficients., Les propriétés de transport à haute température dans les gaz et/ou dans les plasmas ont une importance capitale dans différents domaines, à savoir dans le domaine de technologie de coupure à arc, plasmas de coupure, de soudure ou de gravure. La connaissance des coefficients de transport est nécessaire pour toute modélisation faisant intervenir les équations hydrodynamiques. Dans le cadre de la théorie cinétique des gaz dilués, une solution approchée de l’équation intégro-différentielle de Boltzmann régissant les fonctions de distribution a été proposée par Chapman-Enskog. Les coefficients de transport sont calculés classiquement par la méthode de Chapman-Enskog via les intégrales de collision. Dans le cadre de notre étude nous avons développé, dans un premier temps, un code numérique permettant l’obtention de ces intégrales de collision en tenant compte des singularités qui peuvent apparaître dans le calcul des sections efficaces relatives aux interactions entre les particules constituant les gaz et/ou les plasmas. Dans un second temps nous avons étudié l’influence du choix des paramètres des potentiels d’interaction sur les coefficients de transport. Par la suite, nous avons utilisé le code numérique ainsi développé pour évaluer les coefficients de transport du plasma d’hélium en étudiant l’influence du choix de la méthode de calcul de composition chimique sur ces coefficients. Enfin, un modèle simplifié d’une interaction entre une onde électromagnétique et un plasma d’hélium a été proposé comme une application directe des coefficients de transport.

Abstract: The production of prompt D$_s^+$ mesons was measured for the first time in collisions of heavy nuclei with the ALICE detector at the LHC. The analysis was performed on a data sample of Pb-Pb collisions at a centre-of-mass energy per nucleon pair, $\sqrt{s_{\rm NN}}$, of 2.76 TeV in two different centrality classes, namely 0-10% and 20-50%. D$_s^+$ mesons and their antiparticles were reconstructed at mid-rapidity from their hadronic decay channel D$_s^+\rightarrow��^+$, with $��\rightarrow$K$^-$K$^+$, in the transverse momentum intervals $4< p_{\rm T}, 27 pages, 6 captioned figures, 4 tables, authors from page 22, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/1883

Abstract: Measurements of the fractional momentum loss ($S_{\rm loss}\equiv{\delta}p_T/p_T$) of high-transverse-momentum-identified hadrons in heavy ion collisions are presented. Using $\pi^0$ in Au$+$Au and Cu$+$Cu collisions at $\sqrt{s_{_{NN}}}=62.4$ and 200 GeV measured by the PHENIX experiment at the Relativistic Heavy Ion Collider and and charged hadrons in Pb$+$Pb collisions measured by the ALICE experiment at the Large Hadron Collider, we studied the scaling properties of $S_{\rm loss}$ as a function of a number of variables: the number of participants, $N_{\rm part}$, the number of quark participants, $N_{\rm qp}$, the charged-particle density, $dN_{\rm ch}/d\eta$, and the Bjorken energy density times the equilibration time, $\varepsilon_{\rm Bj}\tau_{0}$. We find that the $p_T$ where $S_{\rm loss}$ has its maximum, varies both with centrality and collision energy. Above the maximum, $S_{\rm loss}$ tends to follow a power-law function with all four scaling variables. The data at $\sqrt{s_{_{NN}}}$=200 GeV and 2.76 TeV, for sufficiently high particle densities, have a common scaling of $S_{\rm loss}$ with $dN_{\rm ch}/d\eta$ and $\varepsilon_{\rm Bj}\tau_{0}$, lending insight on the physics of parton energy loss., Comment: 630 authors, 21 pages, 16 figures, 7 tables. v2 is version accepted by Phys.

Abstract: International audience; Geophysical data allowed the construction of a ~250-km-long lithospheric-scale balanced cross section of the southern Black Sea margin (Espurt et al. 2014). In this paper we combine structural field data, stratigraphic data, and fault kinematics analyses with the 70 km-long onshore part of the section to reconstruct the geodynamic evolution of the Central Pontide orogen. These data reveal new aspects of the structural evolution of the Pontides since the Early Cretaceous. The Central Pontides is a doubly vergent orogenic wedge that results from the inversion of normal faults. Extensional subsidence occurred with an ENE-trend from Aptian to Paleocene in a forearc setting. We infer that the Black Sea back-arc basin also opened during this period, which was also the period of subduction of the Tethys Ocean below the Pontides. As in the Western Pontides, the Cretaceous-Paleocene subsidence was interrupted from Latest Albian to Coniacian time by uplift and erosion that was probably related to a block collision and accretion in the subduction zone. The restoration of the section to its pre-shortening state (Paleocene) shows that fault-related subsidence locally reached 3600 m within the forearc basin. Structural inversion occurred from Early Eocene to Mid-Miocene as a result of collision and indentation of the Pontides by the Kırşehir continental block to the south, with 27.5 km (~28%) shortening along the section studied. The inversion was characterized by NNE-trending shortening that predated the Late Neogene dextral escape of Anatolia along the North Anatolian Fault and the modern stress field characterized by NW-trending compression within the Eocene Boyabat basin.

Abstract: The Standard Model (SM), as the fundamental theory for particle physics, provides an description for fundamental interactions: the eletro-magnetic, weak and strong forces. So far it has been tested by various world-wide experiments. There are questions yet to be answered for the completeness of this theory. We've built up high energy physics experiments to create the particle interactions up to high energy scales. The data from those experiments will offer us chance for testing our understanding of the SM and searching for physics beyong the SM.At the European Organization for Nuclear Research (CERN), the physicists and engineers from all over the world are devoted to discover the fundamental element in the universe. The world's largest and most sophisticated experimental instruments are built up, which accelerate particles to the energy of 3.5-4 \TeV and let them collide at the center of detectors. In this way the physicists are able to find tracks about the way particles interact, and further inspired towards the laws of the nature.A Toroidal LHC ApparatuS (ATLAS), as one of the four main detectors of Large Hadron Collider (LHC) at CERN, aims at a wide range of physics, including the precision measurement of the SM processes, the search for the Higgs bosons, extra dimensions, dark matter and so on. It has the similar purpose as the CMS experiment at the LHC.In ATLAS, di-boson production is one of the most important electro-weak processes. Among the massive vector boson pair production processes, ${W^+W^-}$ has larger cross section compared to ${WZ}$ and ${ZZ}$ production. The electro-weak sector of the SM, as well as the strong interactions, can be tested through precision measurements of the ${W^+W^-}$ production cross section. A measurement of $W^+W^-$ production cross section is performed with a data sample collected in proton-proton collisions at center-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 20.3 fb$^{-1}.$The $W^{+}W^{-}$ events are selected with 3 final states: $ee$, $e\mu$, and $\mu\mu$. In order to suppress the background contamination, mainly from the Drell-Yan and $t\bar{t}$ processes, we cut on missing transverse energy and select events with 0 selected jet. The major backgrounds, mainly including the $W$+jets, top, $Z$+jets, are estimated by data-driven technique. These background estimations are cross-checked by independent methods. The measured cross section is \WZtotXsec$^{+\WZtotXsecStatErrUp}_{\WZtotXsecStatErrDw}$(stat)$^{+\WZtotXsecSysErrUp}_{\WZtotXsecSysErrDw}$(syst)$^{+\WZtotXsecLumiErrUp}_{\WZtotXsecLumiErrDw}$(lumi) pb, which is consistent with SM Next-Leading Order prediction of $63.2^{+2.0}_{-1.8}$ pb.The normalized differential $W^+W^-$ cross section $\frac{1}{\sigma}\frac{d\sigma}{dX}$ is determined as a function of 6 kinematic variables. The unfolding distribution for these variables are given. The possible deviation from the SM can be parameterized with operators of higher order dimensions. The operators of lowest dimension introduce anomalous triple gauge couplings (ATGC). The distribution of leading lepton \pt is used to constrain the anomalous coupling constants. The measurement of the coupling constants provides an indirect search for new physics at mass scales not accessible by the LHC. In our study, no evidence for anomalous $WWZ$ and $WW\gamma$ triple gauge-boson couplings is found, and limits on their magnitudes are set., Le Modèle Standard (MS), théorie fondamentale de la physique des particules, fournit une description de plusieurs interactions fondamentales,les forces électromagnétique, forte et faible. Cette théorie a été testée par nombre d'expériences de par le monde. Il subsiste toutefois certaines questions non résolues par le Modèle Standard,témoignant de la nécessité de disposer d'une théorie plus complète. Les expériences de physique des hautes énergies ont été conçues pour étudier les interactions entre particules à une échelle d'énergie de plus en plus élevée. Les données obtenues par ces expériences offrent la possibilité de tester plus profondément le Modèle Standard, ainsi que de chercher des signes de physique au-delà des prédictions du Modèle Standard.Au Centre Européen pour la Recherche Nucléaire (CERN), des physiciens et ingénieurs du monde entier cherchent à comprendre les lois fondamentales régissant l'Univers. C'est au CERN qu'ont été construits les instruments expérimentaux les plus imposants et les plus sophistiqués, accélérant des faisceaux de particules à une énergie de 3.5-4 TeV pour les faire entrer en collision au centre des détecteurs. De cette manière, les physiciens sont en mesure d'obtenir des indications quant à la manière dont les particules interagissent, dans l'espoir d'appréhender la fondation des lois de la nature.L'expérience ATLAS (A Toroidal Lhc ApparatuS), un des quatre principaux détecteurs installés auprès du LHC (Large Hadron Collider) au CERN, couvre un large spectre de mesures physiques, incluant des mesures de précision pour les processus prévus par le Modèle Standard, la recherche du boson de Higgs, ou encore de nouvelles dimensions, de Matière Noire\ldots L'expérience CMS joue un rôle similaire.Dans le programme d'ATLAS, la production de paires de bosons est l'un des processus électrofaibles les plus intéressants à étudier. Parmi les différents modes de production de paires de bosons vecteurs massifs, la section efficace ${pp\to W^+W^-}$ est la plus importante, comparée aux processus ${WZ}$ ou ${ZZ}$. Le secteur électrofaible du Modèle Standard, ainsi que les interaction fortes, peuvent être testés par la mesure précise de la section efficace de production de paires ${W^+W^-}$. Ce document présente une mesure de cette section efficace à partir d'un lot de collisions proton-proton, à une énergie au centre de masse de 8 TeV, et correspondant à une luminosité intégrée de 20.3 fb$^{-1}.$Les événements $W^{+}W^{-}$ sont sélectionnés à partir de trois états finaux : $ee$, $e\mu$, and $\mu\mu$. Afin de réduire le bruit de fond, constitué principalement de processus Drell-Yan ou de paires $t\bar{t}$, une coupure est appliquée sur l'énergie transverse manquante, et les événements contenant des jets hadroniques satisfaisant certains critères de sélection sont rejetés. Les principaux bruits de fonds résiduels, essentiellement des processus $W$+jets, top, $Z$+jets, sont estimés à l'aide de modèles établis à partir des données observées (méthodes \textit{data driven}). Ces méthodes d'estimation sont validées en les comparant à d'autres méthodes indépendantes. La section efficace mesurée est \WZtotXsec$^{+\WZtotXsecStatErrUp}_{\WZtotXsecStatErrDw}$(stat) $^{+\WZtotXsecSysErrUp}_{\WZtotXsecSysErrDw}$(syst)$^{+\WZtotXsecLumiErrUp}_{\WZtotXsecLumiErrDw}$(lumi) pb, en accord avec la prédiction NLO du Modèle Standard $63.2^{+2.0}_{-1.8}$ pb.Les sections efficaces différentielles normalisées $\frac{1}{\sigma}\frac{d\sigma}{dX}$ sont obtenues pour six différentes variables cinématiques. Les distributions de ces variables, déconvoluées de l'efficacité de reconstruction du détecteur, sont présentées. Les éventuelles déviations de la section efficace mesurée par rapport à la prédiction du Modèle Standard peuvent être paramétrées par des opérateurs de dimension supérieures. Les opérateurs de dimension la plus basse induisent des couplages tri-bosons de jauge anomaux (\tetxtit{ATGC}). La distribution de l'impulsion transverse maximale parmi les deux leptons de l'événement est utilisée pour contraindre ces couplages anomaux. Ainsi, les mesures des constantes de couplage permettent une recherche indirecte de physique au-delà du Modèle Standard, à une échelle de masse non accessible par le LHC. L'étude présentée ici n'a pas mis en évidence de tels couplages anomaux $WWZ$ ou $WW\gamma$, permettant l'établissement de limites supérieures sur la magnitude de ces couplages.
