Abstract: A better knowledge of $(n,xn)$ reaction cross sections is important for both reaction modeling and energy applications. This article focuses on inelastic scattering of neutrons off $^{238}\mathrm{U}$ for which improvements are needed to better constrain evaluations and solve inconsistencies in nuclear power reactor calculations. A new precise measurement of $(n,xn\ensuremath{\gamma})$ reaction cross sections on $^{238}\mathrm{U}$ has been performed at the GELINA (Geel Electron LINear Accelerator) neutron facility operated by EC-JRC-Geel (Belgium) with the GRAPhEME (GeRmanium array for Actinides PrEcise MEasurements) setup. The prompt $\ensuremath{\gamma}$-ray spectroscopy method coupled to time-of-flight measurements is used to extract $(n,xn\ensuremath{\gamma})$ cross section values which can be further combined to infer the total neutron inelastic scattering cross section. Cross section data for 18 $\ensuremath{\gamma}$ transitions (five never measured before) are presented and compared to the data in the literature. Emphasis is especially given to the uncertainty determination to produce partial cross section data as accurate as possible. Due to intrinsic limitations of the experimental method, the use of additional nuclear structure information coupled with theoretical modeling is required to determine the total $(n,{n}^{\ensuremath{'}})$ cross section over the whole neutron energy range. We have investigated modeling aspects of the $^{238}\mathrm{U}(n,{n}^{\ensuremath{'}}\ensuremath{\gamma})$ cross sections related to the description of compound nucleus and preequilibirum mechanisms as well as the discrete part of nuclear structure. Through comparison between experimental and calculated $(n,{n}^{\ensuremath{'}}\ensuremath{\gamma})$ cross sections, we pinpoint inaccuracies in the description of specific reaction mechanisms and challenge recently implemented models. This helps improving the whole modeling of the $(n,{n}^{\ensuremath{'}})$ reaction.

Abstract: The joint evaluated fission and fusion nuclear data library 3.3 is described. New evaluations for neutron-induced interactions with the major actinides U , U and Pu , on Am and Na , Ni , Cr, Cu, Zr, Cd, Hf, W, Au, Pb and Bi are presented. It includes new fission yields, prompt fission neutron spectra and average number of neutrons per fission. In addition, new data for radioactive decay, thermal neutron scattering, gamma-ray emission, neutron activation, delayed neutrons and displacement damage are presented. JEFF-3.3 was complemented by files from the TENDL project. The libraries for photon, proton, deuteron, triton, helion and alpha-particle induced reactions are from TENDL-2017. The demands for uncertainty quantification in modeling led to many new covariance data for the evaluations. A comparison between results from model calculations using the JEFF-3.3 library and those from benchmark experiments for criticality, delayed neutron yields, shielding and decay heat, reveals that JEFF-3.3 performes very well for a wide range of nuclear technology applications, in particular nuclear energy., Acknowledgements The authors would like to thank all contributors to the JEFF project that shared their insights and provided their specific input for the present JEFF-3.3 evaluation and its immediate predecessors JEFF-3.2 and JEFF-3.1.2.

Abstract: The mathematical models used for nuclear data evaluations contain a large number of theoretical parameters that are usually uncertain. These parameters can be calibrated (or improved) by the information collected from integral/differential experiments. The Bayesian inference technique is used to utilize measurements for data assimilation. The Bayesian approximation is based on the least-square or Monte-Carlo approaches. In this process, the model parameters are optimized. In the adjustment process, it is essential to include the analysis related to the influence of model parameters on the adjusted data. In this work, some statistical indicators such as the concept of Cook’s distance; Akaike, Bayesian and deviance information criteria; effective degrees of freedom are developed within the CONRAD platform. Further, these indicators are applied to a test case of 155Gd to evaluate and compare the influence of resonance parameters.

Abstract: In the international neutron libraries, the behavior with the energy of the neutron cross sections of hydrogen in light water depends on the Thermal Scattering Laws tabulated in terms of S ( α , β ) . For the Joint Evaluated Fission and Fusion library (JEFF), Mattes and Keinert have established Thermal Scattering Laws by using the LEAPR module of the NJOY code. However, uncertainties on the corresponding S ( α , β ) were never reported. Such missing information was recently calculated with the nuclear data code CONRAD by determining the covariances between the model parameters involved in LEAPR. The obtained uncertainties were propagated to reactivity coefficients calculated for critical assemblies operating in “cold” conditions (temperature below 80 °C) and for PWR in “hot” operating conditions (300 °C). For the integral benchmarks investigated in this work, we found that the uncertainty on the calculated k eff , due to the S ( α , β ) uncertainties, is close to ± 130 pcm at room temperature and ± 50 pcm at 300 °C.

Abstract: Nuclear data used in designing of various nuclear applications (e.g., core design of reactors) is improved by using integral experiments. To utilize the past critical experimental data to the reactor design work, a typical procedure for the nuclear data adjustment is based on the Bayesian theory (least-square technique or Monte-Carlo). In this method, the nuclear data parameters are optimized by the inclusion of the experimental information using a Bayesian inference. The selection of integral experiments is based on the availability of well-documented specifications and experimental data. Data points with large uncertainties or large residuals (outliers) may affect the accuracy of the adjustment. Hence, in the adjustment process, it is very important to study the influence of experiments as well as of the prior nuclear data on the adjusted results. In this work, the influence of each individual reaction (related to nuclear data) is analyzed using the concept of Cook’s distance. First, JEZEBEL (Pu239, Pu240 and Pu241) integral experiment is considered for data assimilation and then the transposition of results on ASTRID fast reactor concept is discussed.

Abstract: WONDER-2018 – 5th International Workshop On Nuclear Data Evaluation for Reactor applications. 8-12 octobre 2018, Aix-en-Provence, France; International audience; Nuclear decay heat is a crucial issue for PWR in-core safetyafter reactor shutdown and back-end cycle. It is a dimensioning parameterfor safety injection systems (SIS) to avoid a dewatering of the reactor core.The decay heat uncertainty needs to be controlled over the largest range ofapplications. The assimilation of the MERCI-1 experiment was studied toprovide feedbacks on nuclear data. This experiment consisted in themeasurement of the decay heat of a PWR UOX fuel sample irradiated inthe OSIRIS reactor, for cooling times between 45 minutes and 42 days.More specifically, the consideration of several experimental values ofMERCI-1 at different cooling times was tested. This raised issues aboutcorrelations to consider between different measurements. Besides, theimpact of considering correlations between independent fission yields incovariance matrices on the decay heat uncertainty calculation and on thefeedbacks on nuclear data is discussed.

Abstract: OSMOSE was a CEA/DOE collaborative experiment dedicated to the improvement of actinide nuclear data. Based on reactivity worth measurements of pure isotopic samples of various actinides from 232Th to 245Cm, it represents a unique set experimental data to validate evaluated nuclear data. This paper presents the analysis of the experiments conducted in a MOXLWR-type core configuration, with TRIPOLI-4® Monte-Carlo calculations. The comparison between calculated and measured reactivity worth shows a good agreement with JEFF-3.1.1 for all the actinides, except 241Am. The combination of the C/E results with the sensitivity coefficients and prior covariances in a re-estimation process suggests that some improvement is required on the 241Am (n,g), towards an increase of +6% of the JEFF-3.1.1 thermal capture cross section. Based on the same reestimation process, improvements in the nuclear data covariances are pointed out, with posterior uncertainties on the reactivity worth significantly reduced for 238Pu, 239Pu, 241Am, 237Np and 244+245Cm.

Abstract: Neutron resonances observed in neutron cross section data can only be compared with their theoretical analogues after a correct broadening of the resonance widths. This broadening is usually carried out by two different theoretical models, namely the Free Gas Model and the Crystal Lattice Model, which, however, are only applicable under certain assumptions. Here, we use neutron transmission experiments on UO2 samples at $T=23.7$ K and $T=293.7$ K, to investigate the limitations of these models when an ab initio phonon spectrum is introduced in the calculations. Comparisons of the experimental and theoretical transmissions highlight the underestimation of the energy transferred at low temperature and its impact on the accurate determination of the radiation widths $\Gamma_{\gamma_{\lambda}}$ of the 238U resonances $\lambda$ . The observed deficiency of the model represents an experimental evidence that the Debye-Waller factor is not correctly calculated at low temperature near the Neel temperature ( $ T_{N}=30.8$ K).

Abstract: International audience; Nuclear data, along with numerical methods and the associated calculation schemes, continue to play a key role in reactor design, reactor core operating parameters calculations, fuel cycle management and criticality safety calculations. Due to the intensive use of Monte-Carlo calculations reducing numerical biases, the final accuracy of neutronic calculations increasingly depends on the quality of nuclear data used. This paper gives a broad picture of all ingredients treated by nuclear data evaluators during their analyses. After giving an introduction to nuclear data evaluation, we present implications of using the Bayesian inference to obtain evaluated cross sections and related uncertainties. In particular, a focus is made on systematic uncertainties appearing in the analysis of differential measurements as well as advantages and drawbacks one may encounter by analyzing integral experiments.The evaluation work is in general done independently in the resonance and in the continuum energy ranges giving rise to inconsistencies in evaluated files. For future evaluations on the whole energy range, we call attention to two innovative methods used to analyze several nuclear reaction models and impose constraints. Finally, we discuss suggestions for possible improvements in the evaluation process to master the quantification of uncertainties. These are associated with experiments (microscopic and integral), nuclear reaction theories and the Bayesian inference.

Abstract: Nuclear data improvement, validation and completion are one of the major concerns for ensuring safety-by-design standards and economic optimization for modern nuclear facilities. Uncertainty and sensitivity analyses must be carried out to estimate the nuclear data influence on integral reactor parameters, highlighting margins of improvement needed to get full benefit from modern advanced modeling. The quality of any uncertainty quantification analysis strongly depends on the covariance matrices made available in the evaluated nuclear data libraries. In modern nuclear data libraries (e.g. JEFF, ENDF/B or JENDL) no correlations for fission yields (FY) are provided, so in the present work we propose a covariance generation methodology which yielded reasonable results for application-relevant thermal and fast neutron-induced fission product yields. The main goal was not to perform a new evaluation but to reproduce coherently the JEFF-3.1.1 fission yield library and add covariance information. We did so using the Generalized Least Square Method (GLSM) and the Marginalization techniques implemented in the CONRAD code, developed at CEA-Cadarache. Results on the thermal neutron-induced fission of 235 U , 239 Pu , 241 Pu and on the fast-neutron induced fission of 238 U , 239 Pu and 240 Pu are presented and tested on elementary fission decay heat uncertainty quantifications.

Abstract: The CIELO collaboration has studied neutron cross sections on nuclides that significantly impact criticality in nuclear technologies – 16 O, 56 Fe, 235,8 U and 239 Pu – with the aim of improving the accuracy of the data and resolving previous discrepancies in our understanding. This multi-laboratory pilot project, coordinated via the OECD/NEA Working Party on Evaluation Cooperation (WPEC) Subgroup 40 with support also from the IAEA, has motivated experimental and theoretical work and led to suites of new evaluated libraries that accurately reflect measured data and also perform well in integral simulations of criticality.

Abstract: An analysis is presented of inclusiveπ 0 production inZ 0 decays measured with the DELPHI detector. At low energies,π 0 decays are reconstructed by using pairs of converted photons and combinations of converted photons and photons reconstructed in the barrel electromagnetic calorimeter (HPC). At high energies (up to $$x_p = 2 \cdot p_\pi /\sqrt s = 0.75$$ ) the excellent granularity of the HPC is exploited to search for two-photon substructures in single showers. The inclusive differential cross section is measured as a function of energy forqq andbb events. The number ofπ 0’s per hadronicZ 0 event isN(π 0)/Z 0 =9.2±0.2(stat)±1.0(syst) and forbb events the number ofπ 0’s is N(π 0)/bb=10.1±0.4(stat)±1.1(syst). The ratio of the number ofπ 0’s inbb events to hadronicZ 0 events is less affected by the systematic errors and is found to be 1.09±0.05±0.01. The measuredπ 0 cross sections are compared with the predictions of different parton shower models. For hadronic events, the peak position in theξ p=ln(1/xp) distribution isξ* p =3.90 −0.14 +0.24 . The average number ofπ 0’s from the decay of primary B hadrons is found to be N(B→π 0 X)/B hadron=2.78±0.15(stat)±0.60(syst).

Abstract: A search for stable or long-lived heavy charged particles in e+e− interactions at energies of 130–136, 161 and 172 GeV has been performed using the data taken by the DELPHI experiment at LEP. The search is based on particle identification provided by the Time Projection Chamber and the Ring Imaging Cherenkov detector. Upper limits at 95% confidence level are derived on the cross-section for heavy long-lived pair-produced charge ±e and View the MathML source particles in the range of 0.4–2.3 pb for masses from 45 to 84 GeV/c2. Within supersymmetric extensions of the Standard Model, long-lived charginos with masses from 45 to 84 (80) GeV/c2 for high (low) sneutrino masses can be excluded at 95% confidence level. Left-handed (right-handed) long-lived or stable smuons and staus with masses between 45 and 68 (65) GeV/c2 can be excluded at 95% confidence level.

Abstract: We have searched for excited states of charged and neutral leptons, e∗, μ ∗ , τ ∗ and ν ∗ , in e+e− collisions at s =130 using the OPAL detector at LEP. No evidence for their existence was found. With the most common coupling assumptions, the final states from excited lepton pair production include l+l−γγ and l+l−WW (with the subsequent decay of the virtual W bosons). From the analysis of these final states, 95% confidence level lower mass limits of 66.5 GeV for e∗, 66.8 GeV for μ ∗ , 65.3 GeV for τ ∗ , 66.2 GeV for ν e ∗ , 66.5 GeV for ν μ ∗ and 64.7 GeV for ν τ ∗ are inferred. From the analysis of γγ final states with missing energy and using alternative coupling assignments which permit photonic ν ∗ decays, a 95% confidence level lower mass limit of 65.0 GeV for each ν ∗ flavour is inferred. From the analysis of the l+l−γ, acoplanar lepton pair, and single γ final states expected from excited lepton single production, upper limits on f Λ (ratio of the coupling to the compositeness scale) are determined for excited lepton masses up to the kinematic limit.

The signal is compatible with the prediction of the Standard Model for the process View the MathML source, and the number of neutrino families has been determined to be Nν = 3.1 ± 0.6. Limits have been derived on anomalous neutral gauge boson couplings and on compositeness in the framework of a specific model.

Abstract: During the last 1995 data acquisition period at LEP, the DELPHI experiment collected an integrated luminosity of 5.9 pb−1 at centre-of-mass energies of 130 GeV and 136 GeV. Radiative leptonic events (e, μ, τ) with high energy photons were studied and compared to Standard Model predictions. The data were used to search for charged excited leptons decaying through an electromagnetic transition. No significant signal was found. From the search for pair produced excited leptons, the limits View the MathML source, View the MathML source and View the MathML source at 95% confidence level were established. For single excited lepton production, upper limits on the ratio View the MathML source of the coupling of the excited charged lepton to its mass were derived.

Abstract: From the data collected by DELPHI at LEP in autumn 1995, the multiplicity of charged particles at a hadronic energy of 130 GeV has been measured to be 〈nch〉 = 23.84 ± 0.51 (stat) ± 0.52 (syst). When compared to lower energy data, the value measured is consistent with the evolution predicted by QCD with corrections at next-to-leading order, for a value αs(130 GeV) = 0.105 ± 0.003 (stat) ± 0.008 (syst).

Abstract: A measurement of B meson lifetimes is presented using data collected from 1991 to 1993 by the DELPHI detector at the LEP collider. Samples of events with a D meson and a lepton in the same jet are selected where$\bar D^{^0 } \ell ^ + $ and D*l+ events originate mainly from the semileptonic decays of B+ and B0 mesons, respectively. From the reconstructed B decay length and the estimated B momentum, taking into account the dilution due to B decays into$\bar D^{^{**} } \ell ^ + v$, the following B meson lifetimes and lifetime ratio are measured: $$\begin{gathered} \tau (B^ + ) = 1.61_{ - 0.16}^{ + 0.16} (stat.) \pm 0.12(syst.) ps \hfill \\ \tau (B^0 ) = 1.61_{ - 0.13}^{ + 0.14} (stat.) \pm 0.08(syst.) ps \hfill \\ \tau (B^ + )/\tau (B^0 ) = 1.00_{ - 0.15}^{ + 0.17} (stat.) \pm 0.10(syst.) \hfill \\ \end{gathered} $$ and an average lifetime of B+ and B0 mesons is obtained: $$\tau (B) = 1.61_{ - 0.07}^{ + 0.08} (stat.) \pm 0.05(syst.) ps$$

Abstract: A sample of events enriched in bb̄ quark pairs was selected in the data recorded by the DELPHI experiment at LEP during 1992 and 1993, by the presence of secondary decay vertices from short-lived particles. Using this sample, the average multiplicities of Ks0, K±, p(p̄), Λ(View the MathML source) and of charged particles in bb̄ events have been measured, distinguishing the component from fragmentation and the component coming from the decay of b-hadrons. The measurement of the average charge multiplicity in bb̄ events was used to compute the mean fractional beam energy carried by the primary b-hadron, and the difference in charged particle multiplicity between bb̄ events and light quark (uū, dd̄, ss̄) events.

Abstract: Experimental evidence for the existence of orbitally excited B meson states is presented in an analysis of the BÏ and B*Ï distribution of Q = m(B**) - m(B(*)) - m(Ï) using Z0decay data taken with the DELPHI detector at LEP. The mean Q-value of the decays B**â B(*)Ï is measured to be 284 Â± 5 (stat.) Â± 15 (syst.) MeV/c2, and the Gaussian width of the signal is 79 Â± 5 (stat.) Â± 8 (syst.) MeV/c2. This signal can be described as a single resonance of mass m = 5732 Â± 5 (stat.) Â± 20 (syst.) MeV/c2and full width Î = 145 Â± 28 MeV/c2. The observed shape is also consistent with the production of several broad and narrow states as predicted by the quark model and partly observed in the D-meson sector. The production rate of B**per b-jet is found to be 0.27 Â± 0.02 (stat.) Â± 0.06 (syst.). Â© 1995.

Abstract: Recent safety and economical concerns for modern nuclear reactor applica- tions have fed an outstanding interest in basic nuclear data evaluation improvement and completion. It has been immediately clear that the accuracy of our predictive simulation models was strongly affected by our knowledge on input data. Therefore strong efforts have been made to improve nuclear data and to generate complete and reliable uncertainty information able to yield proper uncertainty propagation on integral reactor parameters. Since in modern nuclear data banks (such as JEFF-3.1.1 and ENDF/BVII.1) no correla- tions for fission yields are given, in the present work we propose a covariance generation methodology for fission product yields. The main goal is to reproduce the existing Euro- pean library and to add covariance information to allow proper uncertainty propagation in depletion and decay heat calculations. To do so, we adopted the Generalized Least Square Method (GLSM) implemented in CONRAD (COde for Nuclear Reaction Analysis and Data assimilation), developed at CEA-Cadarache. Theoretical values employed in the Bayesian parameter adjustment are delivered thanks to a convolution of different models, representing several quantities in fission yield calculations: the Brosa fission modes for pre-neutron mass distribution, a simplified Gaussian model for prompt neutron emission probability, the Wahl systematics for charge distribution and the Madland-England model for the isomeric ratio. Some results will be presented for the thermal fission of U-235, Pu-239 and Pu-241.

Abstract: A new IAEA Coordinated Research Project (CRP) aims to test, validate and improve the IRDF library. Among the isotopes of interest, the modelisation of the 238 U capture and fission cross sections represents a challenging task. A new description of the 238 U neutrons induced reactions in the fast energy range is within progress in the frame of an IAEA evaluation consortium. The Nuclear Data group of Cadarache participates in this effort utilizing the 238 U spectral indices measurements and Post Irradiated Experiments (PIE) carried out in the fast reactors MASURCA (CEA Cadarache) and PHENIX (CEA Marcoule). Such a collection of experimental results provides reliable integral information on the (n,γ) and (n,f) cross sections. This paper presents the Integral Data Assimilation (IDA) technique of the CONRAD code used to propagate the uncertainties of the integral data on the 238 U cross sections of interest for dosimetry applications.

Abstract: Proc on line; International audience; The status of the Joint Evaluated Fission and Fusion file (JEFF) is described. JEFF-3.1 comprises a significant update of actinide evaluations, materials evaluations that have emerged from various European nuclear data projects, the activation library JEFF-3.1/A, the decay data and fission yield sub-libraries, and fusion-related data files from the EFF project. The revisions were motivated by the availability of new measurements, modelling capabilities and trends from integral experiments. Validations have been performed, mainly for criticality, reactivity temperature coefficients, fuel inventory and shielding of thermal and fast systems. Compared with earlier releases, JEFF-3.1 provides improved performance with respect to a variety of scientific and industrial applications. Following on from the public release of JEFF-3.1, the French nuclear power industry has selected this suite of nuclear applications libraries for inclusion in their production codes.

Abstract: In the last decade benchmark experiments and simulations, together with newly obtained neutron cross section data, have pointed out deficiencies in evaluated data files of W isotopes. The role of W as a fundamental structural material in different nuclear applications fully justifies a new evaluation of 182, 183, 184, 186W neutron resonance parameters. In this regard transmission and capture cross section measurements on natural and enriched tungsten samples were performed at the GELINA facility of the EC-JRC-IRMM. A resonance parameter file used as input in the resonance shape analysis was prepared based on the available literature and adjusted in first instance to transmission data. © Owned by the authors, published by EDP Sciences, 2013.

Abstract: In a sample of 3.02 million hadronic $Z^o$ decays collected by the DELPHI detector, 270 $J/\psi \into$ \lplm candidates have been selected. A search for fully reconstructed $B_c\upm$ mesons has yielded one $B_c\upm\to J/\psi ~\pi\upm$ candidate, no $B_c\upm \into J/\psi ~\ell\upm ~\nu_\ell$ candidates, and one $B_c\upm \into J/\psi ~\pi^+~\pi^- ~\pi\upm$ candidate, consistent with expected background in each channel. The following 90\% confidence level upper limits are determined: r(Z^o \into B_c\upm ~X) \times Br(B_c\upm \into J/\psi ~\pi\upm) (1.05~{\mathrm{to}}~0.84) \times 10^{-4} and r(Z^o \into B_c\upm ~X) \times Br(B_c\upm \into J/\psi ~\ell\upm ~\nu_\ell) (5.8~{\mathrm{to}}~5.0) \times 10^{-5}, where the ranges quoted correspond to the range of predicted $B_c\upm$ lifetimes from 0.4 to 1.4 ps, and r(Z^o \into B_c\upm ~X) \times Br(B_c\upm \into J/\psi ~\pi^+ ~\pi^- ~\pi\upm) 1.75 \times 10^{-4}, constant over the range of predicted $B_c\upm$ lifeti

Abstract: An upper limit for BR(Z(0) --> 3g) is obtained from a correlation method, which distinguishes statistically between quark and gluon jets by using the difference in their charged particle multiplicity distributions. From the sample of threefold symmetric three-jet events collected by the DELPHI experiment at LEP during 1991-1994, the 95% confidence level upper limit is deduced to be: BR(Z(0) --> 3g) less than or equal to 1.6 x 10(-2) for the JADE and BR(Z(0) --> 3g) less than or equal to 1.5 x 10(-2) for the DURHAM jet-finder.

Abstract: The hadronic photon structure function F_{2}^{gamma} has been measured in the Q^{2} range from 4 to 30~GeV^2/c^{4} and down to x values of order 0.001, using data taken with the DELPHI detector at LEP between 1991 and 1993. A comparison is made with several F_{2}^{gamma} parameterizations with special emphasis on their low x behaviour. A result on the Q^{2} evolution of F_{2}^{gamma} is presented.

Abstract: The first measurement of like-sign charged kaon correlations in hadronic decays of the Z$^0$ is presented, based on data collected by the DELPHI detector. The charged kaons are identified by means of ring imaging Cherenkov detectors. A significant enhancement at small values of the four-momentum difference is observed in the ratio of like-sign to unlike-sign KK pairs and in the ratio of like-sign pairs to a simulated reference sample. An update of the measurement of \ksks~interference is also presented. An enhancement is found in the production of pairs of \kos of similar momenta, as compared with a simulated reference sample. The measured Bose-Einstein correlation parameters $\lambda$ and $r$ are similar for charged and neutral kaon pairs. The value of the Bose-Einstein correlation strength $\lambda$ is consistent with unity.

Abstract: The average lifetime of b-baryons has been studied using 3 \times 10^6 hadronic Z^0 decays collected by the DELPHI detector at LEP. Three methods have been used, based on the measurement of different observables: the proper decay time distribution of 206 vertices reconstructed with a \Lambda, a lepton and an oppositely charged pion; the impact parameter distribution of 441 muons with high transverse momentum accompanied by a \mLs in the same jet; and the proper decay time distribution of 125 \Lambda_c-lepton decay vertices with the \Lambda_c exclusively reconstructed through its pK\pi, pK^0 and \mLs3\pi decay modes. The combined result is~:\par \begin{center} \tau(b-baryon) = (1.25^{+0.13}_{-0.11}\ pm0.04(syst)^{+0.03}_{-0. 05}(syst)) ps\par \end{center} where the first systematic error is due to experimental uncertainties and the second to the uncertainties in the modelling of the b-baryon production and semi-leptonic decay. Including the measurement recently published by DELPHI based on a sample of proton-muon vertices, the average b-baryon lifetime is ~:\par \begin{center} \tau(b-baryon) = (1.25\pm0.11(stat)\pm0.05(syst)) ps.\par \end{center}

Abstract: The interference between initial and final state radiation in the process \eemm\ at $\sqs \approx \MZ$ has been studied by measuring the forward-backward asymmetry as a function of the acoplanarity angle between the final state muons. The interference is expected to be sensitive to the space-time separation of the initial and final state radiation. The measured asymmetry distribution has been compared to theoretical predictions using the \KORALZ\ generator, with and without Ördalph\ interference. The magnitude of the interference between initial and $ \pm 0.06 $ (syst.) \GeV} . \end{center} has been extracted. The interpretation of this result is discussed. There is an additional uncertainty in the estimate of \GZ\ from as yet uncalculated higher order interference terms. By assuming a value of \GZ\ consistent with the world average, the data were used to estimate the size of these uncalculated corrections. The interference between initial and final state radiation in the process \eemm\ at \sqs \approx \MZ has been studied by measuring the forward-backward asymmetry as a function of the acoplanarity angle between the final state muons.

The measured asymmetry distribution has been compared to theoretical predictions using the \KORALZ\ generator, with and without \ordalph\ interference. The magnitude of the interference between initial and final state radiation was found to be of the order predicted and to follow the expected distribution. Using the theoretical predictions, a value of \begin{center} \mbox{ \GZ = 2.50 \pm 0.21 (stat.) \pm 0.06 (syst.) \GeV} . \end{center} has been extracted. The interpretation of this result is discussed. There is an additional uncertainty in the estimate of \GZ\ from as yet uncalculated higher order interference terms.

Abstract: A search has been made for direct production of heavy quarkonium states in more than 3 million hadronic Z^{0} decays in the 1991-1994 DELPHI data. Prompt J/\psi, \psi(2S) and \Upsilon candidates have been searched for through their leptonic decay modes using criteria based on the kinematics and decay vertex positions. New upper limits are set at the 90 \% confidence level for {Br( Z^0 \rightarrow \left( Q \bar{Q} \right) X ) / Br( Z^0 \rightarrow \mbox{hadrons})} for various strong production mechanisms of J/\psi and \Upsilon; these range down to 0.9 \times 10^{-4}. The limits are set in the presence of a small excess (\sim 1 \% statistical probability of a background fluctuation) in the sum of candidates from prompt J/\psi, \psi(2S), \Upsilon(1S), \Upsilon(2S) and \Upsilon(3S) relative to the estimated background.

Abstract: The tau lepton lifetime has been measured using three different methods with the DELPHI detector. Two measurements of one-prong decays are combined, accounting for correlations, giving a result of \tau_\tau = 291.8 \pm 3.3 \mbox{ (stat.)} \pm 2.0 \mbox{(sys.) fs} while the decay length distribution of three-prong decays gives the result \tau_{\tau} = 286.7 \pm 4.9 \mbox{ (stat.)} \pm 3.3 \mbox{ (sys.) fs}. Combining the results presented here with previous DELPHI measurements, we get \tau_{\tau} = 291.4 \pm 3.0 fs and find that the ratio of the coupling constant for tau decay relative to that for muon decay is 0.990 \pm 0.009, compatible with lepton universality.

Abstract: This analysis, based on a sample of 170000 hadronic Z0 decays, provides a measurement of the K± and p/View the MathML source differential cross sections which is compared to string- and cluster fragmentation models. The total multiplicities for K± and p/View the MathML source per hadronic event were found to be: NK = 2.26 ± 0.18 and Np = 1.07 ± 0.14. The positions ξ* of the maxima of the differential cross sections as a function of ξ = ln(1/xp) for K± and p/View the MathML source were determined to be 2.63 ± 0.07 and 2.96 ± 0.16 respectively. A comparison of the ξ* values for various identified particles measured at LEP with the prediction of the Modified Leading Logarithm Approximation with Local Parton Hadron Duality model has been performed. The measured ξ* position as a function of the hadron mass, after corrections due to particle decays, is in agreement with the model calculation.

Abstract: Two measurements of {Mathematical expression} are presented. Both measurements use 250000 Z decays taken with the DELPHI detector in 1991 and rely mainly on the precision of the microvertex detector. One tagging method is as simple as possible so that background rates can be reliably predicted by simulation. The other one uses a more involved tagging technique and reduces the dependence on simulation as much as possible. Combining both results, {Mathematical expression} is found to be 0.2209±0.0041(stat.)±0.0042(syst.)±0.0018 {Mathematical expression}. © 1995 Springer-Verlag.

Abstract: A sample of Z0→τ+τ- events observed in the DELPHI detector at LEP in 1991 and 1992 is analysed to measure the τ polarisation in the exclusive decay channels {Mathematical expression}, {Mathematical expression}, πν, ρν and a1ν. The τ polarisation is also measured with an inclusive hadronic analysis which benefits from a higher efficiency and a better systematic precision than the use of the exclusive decay modes. The results have been combined with those published on the 1990 data. A measurement of the τ polarisation as a function of production angle yields the values for the mean τ polarisation 〈P〉τ=-0.148±0.022 and for the Z0 polarisation PZ=-0.136±0.027. These results are used to determine the ratio of vector to axial-vector effective couplings for taus {Mathematical expression}, and for electrons {Mathematical expression}, compatible with e-τ universality. With the assumption of lepton universality, the ratio of vector to axial-vector effective couplings for leptons {Mathematical expression} is obtained, implying a value of the effective weak mixing angle sin2θefflept=0.2320±0.0021 . © 1995 Springer-Verlag.

Abstract: The partial decay width of theZ to $$b\bar b$$ quark pairs has been measured by the DELPHI detector at LEP.b-hadrons, containingb-quarks, were tagged by leptons with high transverse momentum relative to the hadron or by tracks with large impact parameters to the primary vertex. The ratio of the numbers of events with a single such tag to those with two tags was used to estimate the efficiency of the method and to reduce the systematic uncertainty. Combining all methods, the value: $$\begin{gathered} \frac{{\Gamma _{b\bar b} }}{{\Gamma _{had} }} = 0.2210 \pm 0.0033 \pm 0.0003(model) \hfill \\ \pm 0.0014(\Gamma _{c\bar c} ) \hfill \\ \end{gathered} $$ was found, where the third error corresponds to a±8% uncertainty on the $$c\bar c$$ production width. A maximum likelihood in to the single and di-lepton distributions gave the branching fraction of the decays ofb-quarks to leptons as: $$\begin{gathered} BR(b \to l) = (11.06 \pm 0.39 \pm 0.19(model) \hfill \\ \pm 0.12(\Gamma _{c\bar c} ))\% . \hfill \\ \end{gathered} $$

Abstract: A search for pair production of neutral heavy Higgs bosons decaying into bb has been carried out in a study of hadronic decays of the Z boson into four jet final states using data taken by DELPHI in 1991 and 1992. The two production mechanisms present in the two Higgs doublets scheme, bremsstrahlung production of hZ* and associated production of hA, may lead to four beauty jets well recognizable using the precise microvertex detector measurements. No evidence for a signal was found, leading to limits on BR(ZrarrhArarr4b) from 3.5 to 5.5×10–4 at 95% contidence level, depending on the mass of the ligthest Higgs. When combined with the results of the recent DELPHI standard Higgs search, this result allows the kinematical limit to be reached for the masses of h and A in the minimal supersymmetric extension of the Standard Model (MSSM) scheme. It also allows the tanbetale1 domain to be explored, and a region above the kinematic limit for direct hA production is constrained by considering virtual hA production. Results are also given in the general two-doublet scheme.

Abstract: The forward-backward asymmetry of the process e+e-→Z→b {Mathematical expression} has been measured using events collected by the DELPHI experiment during the 1991 and 1992 LEP runs. This data sample corresponded to 884 000 hadronic Z decays at a centre-of-mass energy {Mathematical expression}. The tagging of b-quark events was performed using two approaches; the first was based on the semileptonic decay channels b→X+μ and b→X+e, the second used a lifetime tag with jet-charge reconstruction. The results of these two methods were combined to give {Mathematical expression} With the semileptonic sample, the forward-backward asymmetry of the process e+e-→Z→ {Mathematical expression} was also measured to be {Mathematical expression} The effective value of the Weinberg mixing angle derived from these measurements was {Mathematical expression} © 1995 Springer-Verlag.

Abstract: A sample of 25000 Z(0) --> tau(-)tau(+) events collected by the DELPHI experiment at LEP in 1991 and 1992 is used to measure the leptonic branching fractions of the tau lepton. The results are B(tau --> e nu) = (17.51+/-0.39)% and B(tau --> mu nu) = (17.02+/-0.31)%. The ratio of the muon and electron couplings to the weak charged current is measured to be g(mu)/g(e) = 1.000+/-0.013, satisfying e-mu universality. The average leptonic branching fraction corrected to the value for a massless lepton, assuming e-mu universality, is found to be B(tau --> l nu) = (17.50+/-0.25)%.

Abstract: Kaon production in one prong tau decays has been studied using data collected with the DELPHI detector at the LEP collider Charged kaons were identified over a large momentum range by the DELPHI barrel Ring Imaging Cherenkov detector. The following branching ratios have been determined: BR(τ → Kντ) = (0.85 ± 0.18) %, BR(τ → Kντ ≥ 0 neutrals) = (1.54 ± 0.24)%, BR(τ → Kντ ≥ 1 neutrals) = (0.69 ± 0.25)%. The result for the exclusive branching ratio is consistent with the Standard Model prediction based on τ - μ - e universality. In addition, tau decay into K*- was studied in the channel K*- → K-π0. The result BR(τ → K*-ντ) x BR(K*- → K-w0) = (0.57 ± 0.23)% was obtained.

Abstract: The time dependent mixing of View the MathML source mesons has been observed by using the correlations between the charge of D∗ mesons and the weighted mean charge of particles in each hemisphere. From a reconstructed D∗± sample corresponding to about 1.7 million hadronic Z0 decays, the mass difference between the two Bd0 mass eigenstates has been measured to be View the MathML source or, converting into eV/c2: Δm = [3.29 ± 0.79 (stat) ± 0.39 (syst.)] 10−4 eV/c2.

Abstract: J/psi mesons have been reconstructed from their decay to mu(+)mu(-) and e(+)e(-), using the data collected by the DELPHI experiment during 1991 and 1992 at the LEP collider. From about 1 million hadronic Z decays 153 +/- 17 J/psi were found, 5.4 +/- 2.3 psi' were obtained in the channel J/psi(--> mu(+)mu(-))pi(+)pi(-) and 6.4 +/- 2.7 chi(c) in the channel J/psi(--> mu(+)mu(-))gamma. As the dominant source of J/psi mesons is from b quarks, the following branching ratios: Br(b-->J/psi X) = (1.12 +/- 0.12 (stat.) +/- 0.10 (syst.))%, Br(b --> psi' X) = (0.48 +/- 0.22 (stat.) +/- 0.10 (syst.))%, Br(b-->chi(cl) X) = (1.4 +/- 0.6 (stat.)(-0.2)(+0.4) (syst.))% were measured. From the proper time distribution of the J/psi sample, the average lifetime of b-hadrons decaying into J/psi was found to be: tau(B) = 1.50(-0.21)(+0.24) (stat.) +/- 0.03 (syst.) ps. A search for completely reconstructed B meson decays to final states including a J/psi gave a signal of 15 +/- 5 events.

Abstract: In 1996 LEP ran at a centre-of-mass energy of 161~GeV, just above the threshold of W-pair production. DELPHI accumulated data corresponding to an integrated luminosity of $9.93 {\mathrm{~pb^{-1}}}$, and observed 29 events that are considered as candidates for W-pair production. From these, a cross-section for the doubly resonant $e^+e^-\to\mathrm{WW}$ process of $3.67~^{+0.97}_{-0.85} \pm 0.19{\mathrm{~pb}}$ has been measured. Within the Standard Model, this cross-section corresponds to a mass of the W-boson of ${\mathrm{80.40~\pm~0.44~(stat.)~\pm~0.09~(syst.) ~\pm 0.03~(LEP)~GeV}}/c^2$. Alternatively, if $m_{\mathrm{W}}$ is held fixed at its current value determined by other experiments, the observed cross-section is used to obtain limits on trilinear ${\mathrm{WWV (V \equiv \gamma, Z)}}$ couplings.

Abstract: An analysis is reported on the channele+e−→μ+μ−(nγ), n=1,2..., using data taken with the DELPHI detector at LEP from 1990 to 1992. Differential cross sections of the radiative photons as a function of photon energy and of the angle between the photon and the muon are presented. No significant deviations from expectations are observed. The data are also used to extract the muon-pair cross section and asymmetry below the Z0 peak by using those events with relatively hard initial state radiative photon(s). The measured cross section and asymmetry show no significant deviation from the Standard Model expectations. These results together with the DELPHI cross section and asymmetry measurements at the LEP energies from the 1990 to 1992 running periods are used to determine limits on the Z0-Z′ gauge boson mixing angle θZ′ and on the Z′ mass. There is no indication of the existence of a Z′; the limits obtained on the mixing angle substantially improve upon existing limits. The 95% confidence level allowed ranges of θZ′ in various models are: $$\begin{gathered} - 0.0070 \leqslant \theta _{Z'} \leqslant 0.0078,E_6 (\chi )\bmod el, \hfill \\ - 0.0075 \leqslant \theta _{Z'} \leqslant 0.0095,E_6 (\psi )\bmod el, \hfill \\ - 0.029 \leqslant \theta _{Z'} \leqslant 0.029,E_6 (\eta )\bmod el, \hfill \\ - 0.0068 \leqslant \theta _{Z'} \leqslant 0.0082,L - R(1.)\bmod el, \hfill \\ - 0.0057 \leqslant \theta _{Z'} \leqslant 0.0077,L - R(\sqrt 2 )\bmod el. \hfill \\ \end{gathered} $$
