Abstract

The European physical journal / C 82(5), 474 (2022). doi:10.1140/epjc/s10052-022-10402-0, The electroweak (EW) sector of the Minimal Supersymmetric extension of the Standard Model (MSSM), assuming the lightest neutralino as Dark Matter (DM) candidate, can account for a variety of experimental results. This includes the DM direct detection limits, the searches for EW superpartners at the LHC, and in particular the discrepancy between the experimental result for the anomalous magnetic moment of the muon, $(g-2)_\mu $, and its Standard Model (SM) prediction. The new “MUON G-2” result, combined with the older BNL result on $(g-2)_\mu $, yields a deviation from the SM prediction of $\Delta a_\mu = ({25.1}\pm {5.9}) \times 10^{-10}$, corresponding to ${4.2}\,\sigma $. Using this updated bound, together with the other constraints, we calculate the MSSM prediction for the mass of the W boson, $M_W$. We assume contributions only from the EW sector, i.e. the colored sector of the MSSM, in agreement with the search limits, is taken to be heavy. We investigate five scenarios, distinguished by the mechanisms which yield a relic DM density in agreement with the latest Planck bounds. We find that with the new $(g-2)_\mu $ result taken into account and depending on the scenario, values up to are reached. The largest values are obtained for wino DM and in the case of slepton co-annihilation, where points well within the $1\,\sigma $ range of the experimental world average of $M_W^{\mathrm {exp}}= 80.379 \pm 0.012 \,\, \mathrm {GeV}$ are reached, whereas the SM predicts a too small value of $M_W^{\mathrm {SM}}= 80.353 \,\, \mathrm {GeV}$. We analyze the dependence of $M_W^{\mathrm {MSSM}}$ on the relevant masses of the EW superpartners and demonstrate that future $M_W$ measurements, e.g. at the ILC, could distinguish between various MSSM realizations. Sizable contributions to $M_W^{\mathrm {MSSM}}$ are associated with a relatively light $\tilde{\chi }_{1}^0$, accompanied by either a light chargino or a light smuon, setting interesting targets for future collider searches., Published by Springer, Heidelberg

Abstract

Double Higgs Production at Colliders, Batavia, United States, 4 Sep 2018 - 9 Sep 2019; 279 pp. (2020)., This document summarises the current theoretical and experimental status of the di-Higgs boson production searches, and of the direct and indirect constraints on the Higgs boson self-coupling, with the wish to serve as a useful guide for the next years. The document discusses the theoretical status, including state-of-the-art predictions for di-Higgs cross sections, developments on the effective field theory approach, and studies on specific new physics scenarios that can show up in the di-Higgs final state. The status of di-Higgs searches and the direct and indirect constraints on the Higgs self-coupling at the LHC are presented, with an overview of the relevant experimental techniques, and covering all the variety of relevant signatures. Finally, the capabilities of future colliders in determining the Higgs self-coupling are addressed, comparing the projected precision that can be obtained in such facilities. The work has started as the proceedings of the Di-Higgs workshop at Colliders, held at Fermilab from the 4th to the 9th of September 2018, but it went beyond the topics discussed at that workshop and included further developments.

Abstract

We use MasterCode to perform a frequentist analysis of the constraints on a phenomenological MSSM model with 11 parameters, the pMSSM11, including constraints from ∼ 36 /fb of LHC data at 13 TeV and PICO, XENON1T and PandaX-II searches for dark matter scattering, as well as previous accelerator and astrophysical measurements, presenting fits both with and without the (g- 2) μ constraint. The pMSSM11 is specified by the following parameters: 3 gaugino masses M1 , 2 , 3, a common mass for the first-and second-generation squarks mq~ and a distinct third-generation squark mass mq~3, a common mass for the first-and second-generation sleptons mℓ~ and a distinct third-generation slepton mass mτ~, a common trilinear mixing parameter A, the Higgs mixing parameter μ, the pseudoscalar Higgs mass MA and tan β. In the fit including (g- 2) μ, a Bino-like χ~10 is preferred, whereas a Higgsino-like χ~10 is mildly favoured when the (g- 2) μ constraint is dropped. We identify the mechanisms that operate in different regions of the pMSSM11 parameter space to bring the relic density of the lightest neutralino, χ~10, into the range indicated by cosmological data. In the fit including (g- 2) μ, coannihilations with χ~20 and the Wino-like χ~1± or with nearly-degenerate first- and second-generation sleptons are active, whereas coannihilations with the χ~20 and the Higgsino-like χ~1± or with first- and second-generation squarks may be important when the (g- 2) μ constraint is dropped. In the two cases, we present χ2 functions in two-dimensional mass planes as well as their one-dimensional profile projections and best-fit spectra. Prospects remain for discovering strongly-interacting sparticles at the LHC, in both the scenarios with and without the (g- 2) μ constraint, as well as for discovering electroweakly-interacting sparticles at a future linear e+e- collider such as the ILC or CLIC. © 2018, The Author(s).

Abstract

868 pages, 295 figures, 248 tables and 1642 citations. Working Group web page: https://twiki.cern.ch/twiki/bin/view/LHCPhysics/LHCHXSWG; This Report summarizes the results of the activities of the LHC Higgs Cross Section Working Group in the period 2014-2016. The main goal of the working group was to present the state-of-the-art of Higgs physics at the LHC, integrating all new results that have appeared in the last few years. The first part compiles the most up-to-date predictions of Higgs boson production cross sections and decay branching ratios, parton distribution functions, and off-shell Higgs boson production and interference effects. The second part discusses the recent progress in Higgs effective field theory predictions, followed by the third part on pseudo-observables, simplified template cross section and fiducial cross section measurements, which give the baseline framework for Higgs boson property measurements. The fourth part deals with the beyond the Standard Model predictions of various benchmark scenarios of Minimal Supersymmetric Standard Model, extended scalar sector, Next-to-Minimal Supersymmetric Standard Model and exotic Higgs boson decays. This report follows three previous working-group reports: Handbook of LHC Higgs Cross Sections: 1. Inclusive Observables (CERN-2011-002), Handbook of LHC Higgs Cross Sections: 2. Differential Distributions (CERN-2012-002), and Handbook of LHC Higgs Cross Sections: 3. Higgs properties (CERN-2013-004). The current report serves as the baseline reference for Higgs physics in LHC Run 2 and beyond.

Abstract

This Report summarizes the results of the activities in 2012 and the first half of 2013 of the LHC Higgs Cross Section Working Group. The main goal of the working group was to present the state of the art of Higgs Physics at the LHC, integrating all new results that have appeared in the last few years. This report follows the first working group report Handbook of LHC Higgs Cross Sections: 1. Inclusive Observables (CERN-2011-002) and the second working group report Handbook of LHC Higgs Cross Sections: 2. Differential Distributions (CERN-2012-002). After the discovery of a Higgs boson at the LHC in mid-2012 this report focuses on refined prediction of Standard Model (SM) Higgs phenomenology around the experimentally observed value of 125-126 GeV, refined predictions for heavy SM-like Higgs bosons as well as predictions in the Minimal Supersymmetric Standard Model and first steps to go beyond these models. The other main focus is on the extraction of the characteristics and properties of the newly discovered particle such as couplings to SM particles, spin and CP-quantum numbers etc.

Abstract

This Report summarises the results of the second year's activities of the LHC Higgs Cross Section Working Group. The main goal of the working group was to present the state of the art of Higgs Physics at the LHC, integrating all new results that have appeared in the last few years. The first working group report Handbook of LHC Higgs Cross Sections: 1. Inclusive Observables (CERN-2011-002) focuses on predictions (central values and errors) for total Higgs production cross sections and Higgs branching ratios in the Standard Model and its minimal supersymmetric extension, covering also related issues such as Monte Carlo generators, parton distribution functions, and pseudo-observables. This second Report represents the next natural step towards realistic predictions upon providing results on cross sections with benchmark cuts, differential distributions, details of specific decay channels, and further recent developments.

Abstract

This Report summarises the results of the second year's activities of the LHC Higgs Cross Section Working Group. The main goal of the working group was to present the state of the art of Higgs Physics at the LHC, integrating all new results that have appeared in the last few years. The first working group report Handbook of LHC Higgs Cross Sections: 1. Inclusive Observables (CERN-2011-002) focuses on predictions (central values and errors) for total Higgs production cross sections and Higgs branching ratios in the Standard Model and its minimal supersymmetric extension, covering also related issues such as Monte Carlo generators, parton distribution functions, and pseudo-observables. This second Report represents the next natural step towards realistic predictions upon providing results on cross sections with benchmark cuts, differential distributions, details of specific decay channels, and further recent developments

Abstract

We discuss the parameter spaces of supersymmetry (SUSY) scenarios taking into account the improved Higgs-mass prediction provided by FeynHiggs 2.14.1. Among other improvements, this prediction incorporates three-loop renormalization-group effects and two-loop threshold corrections, and can accommodate three separate mass scales: $m_{\tilde q}$ (for squarks), $m_{\tilde g}$ (for gluinos) and $m_{\tilde\chi}$ (for electroweakinos). Furthermore, it contains an improved treatment of the $\overline{DR}$ scalar top parameters avoiding problems with the conversion to on-shell parameters, that yields more accurate results for large SUSY-breaking scales. We first consider the CMSSM, in which the soft SUSY-breaking parameters $m_0$ and $m_{1/2}$ are universal at the GUT scale, and then sub-GUT models in which universality is imposed at some lower scale. In both cases, we consider the constraints from the Higgs-boson mass $M_h$ in the bulk of the $(m_0, m_{1/2})$ plane and also along stop coannihilation strips where sparticle masses may extend into the multi-TeV range. We then consider the minimal anomaly-mediated SUSY-breaking (mAMSB) scenario, in which large sparticle masses are generic. In all these scenarios the substantial improvements between the calculations of $M_h$ in FeynHiggs 2.14.1 and FeynHiggs 2.10.0, which was used in an earlier study, change significantly the preferred portions of the models' parameter spaces. Finally, we consider the pMSSM11, in which sparticle masses may be significantly smaller and we find only small changes in the preferred regions of parameter space.

Abstract

Predictions for the Higgs masses are a distinctive feature of supersymmetric extensions of the Standard Model, where they play a crucial role in constraining the parameter space. The discovery of a Higgs boson and the remarkably precise measurement of its mass at the LHC have spurred new efforts aimed at improving the accuracy of the theoretical predictions for the Higgs masses in supersymmetric models. The “Precision SUSY Higgs Mass Calculation Initiative” (KUTS) was launched in 2014 to provide a forum for discussions between the different groups involved in these efforts. This report aims to present a comprehensive overview of the current status of Higgs-mass calculations in supersymmetric models, to document the many advances that were achieved in recent years and were discussed during the KUTS meetings, and to outline the prospects for future improvements in these calculations., Funded by SCOAP3., The work of S.H. has been supported in part by the MEINCOP (Spain) under contract FPA2016-78022-P and under contract PID2019-110058GB-C21, in part by the Spanish Agencia Estatal de Investigación (AEI), in part by the EU Fondo Europeo de Desarrollo Regional (FEDER) through the project FPA2016-78645-P, in part by the “Spanish Red Consolider MultiDark” FPA2017-90566-REDC, and in part by the AEI through the grant IFT Centro de Excelencia Severo Ochoa SEV-2016-0597.

Abstract

We improve the determination of the Higgs-boson mass in the MSSM with heavy superpartners, by computing the two-loop threshold corrections to the quartic Higgs coupling that involve both the strong and the electroweak gauge couplings. Combined with earlier results, this completes the calculation of the two-loop QCD corrections to the quartic coupling at the SUSY scale. We also compare different computations of the relation between the quartic coupling and the pole mass of the Higgs boson at the EW scale. We find that the numerical impact of the new corrections on the prediction for the Higgs mass is modest, but comparable to the accuracy of the Higgs-mass measurement at the LHC., Comment: 28 pages, 3 pdf figures; v2: reference added, minor textual changes, version published in EPJC

Abstract

The production of a Standard Model Higgs boson in association with two hard jets in the forward and backward regions of the detector, frequently quoted as the “vector-boson fusion” (VBF) channel, and the production of a Higgs boson in association with a W or Z boson, known as “VH production” or “Higgsstrahlung”, represent cornerstones in a comprehensive study of Higgs boson couplings at the LHC. These production channels do not only provide valuable information on the couplings of Higgs bosons to the massive gauge bosons by themselves, but also allow for the isolation of the Higgs boson decays into -lepton or bottom-quark pairs, whose investigation is essential in the Higgs boson couplings analysis. In the previous reports [7–9], state-of-the-art predictions and error estimates for the total and differential cross sections for pp ! H + 2 jets and pp ! HV ! H + 2 leptons were compiled (with V = W; Z), but the process of improving and refining predictions is still ongoing, even within the Standard Model. In this contribution we update the cross-section predictions for VBF and VH production, covering integrated total and fiducial cross sections as well as differential distributions. In detail, the presented state-of-the-art predictions include QCD corrections up to next-to-next-to-leading order (NNLO), electroweak (EW) corrections up to next-to-leading order (NLO), and contributions from specific partonic channels that open at higher perturbative orders, such as photon-induced collisions or gluon-fusion contributions. Apart from collecting numerical results, we give recommendations as to how to combine the individual components and to assess conservative estimates of remaining theoretical uncertainties. Moreover, issues connected to the matching and the impact of parton showers (PS) are discussed.

Abstract

We consider the gluon fusion production cross section of a scalar Higgs boson at NLO QCD in the SM and in the MSSM. We implement the calculation in the POWHEG approach, and match the NLO-QCD results with the PYTHIA and HERWIG QCD parton showers. We discuss a few representative scenarios in the SM and MSSM parameter spaces, with emphasis on the fermion and squark mass effects on the Higgs boson distributions., 27 pages, 36 eps figures; v2: 2 eps figures added, section 3.2 expanded, version published in JHEP

33. Rise and Fall of Light Top Squarks in the LHC Top-Quark Sample.

Author

Bagnaschi E, Corcella G, Franceschini R, and Sengupta D

Abstract

We discuss the possibility that light new physics in the top-quark sample at the LHC can be found by investigating with greater care well-known kinematic distributions, such as the invariant mass m_{bℓ} of the b-jet and the charged lepton in fully leptonic tt[over ¯] events. We demonstrate that new physics can be probed in the rising part of the already measured m_{bℓ} distribution. To this end, we analyze a concrete supersymmetric scenario with a light right-handed top-squark, chargino and neutralino. The corresponding spectra are characterized by small mass differences, which make them not yet excluded by current LHC searches and give rise to a specific end point in the shape of the m_{bℓ} distribution. We argue that this sharp feature is general for models of light new physics that have so far escaped the LHC searches and can offer a precious handle for the implementation of robust searches that exploit, rather than suffer from, soft bottom quarks and leptons. Recasting public data on searches for new physics, we identify candidate models that are not yet excluded. For these models, we study the m_{bℓ} distribution and derive the expected signal yields, finding that there is untapped potential for discovery of new physics using the m_{bℓ} distribution.

Abstract

Physical theories that depend on many parameters or are tested against data from many different experiments pose unique challenges to statistical inference. Many models in particle physics, astrophysics and cosmology fall into one or both of these categories. These issues are often sidestepped with statistically unsound ad hoc methods, involving intersection of parameter intervals estimated by multiple experiments, and random or grid sampling of model parameters. Whilst these methods are easy to apply, they exhibit pathologies even in low-dimensional parameter spaces, and quickly become problematic to use and interpret in higher dimensions. In this article we give clear guidance for going beyond these procedures, suggesting where possible simple methods for performing statistically sound inference, and recommendations of readily-available software tools and standards that can assist in doing so. Our aim is to provide any physicists lacking comprehensive statistical training with recommendations for reaching correct scientific conclusions, with only a modest increase in analysis burden. Our examples can be reproduced with the code publicly available at Zenodo., (© 2022 IOP Publishing Ltd.)

35. Parton Density Uncertainties and the Determination of Electroweak Parameters at Hadron Colliders.

Author

Bagnaschi E and Vicini A

Abstract

We discuss the determination of electroweak parameters from hadron collider observables, focusing on the W-boson mass measurement. We revise the procedures adopted in the literature to include in the experimental analysis the uncertainty due to our imperfect knowledge of the proton structure. We show how the treatment of the proton parton density functions' (PDFs') uncertainty as a source of systematic error leads to the automatic inclusion in the fit of the bin-bin correlation of the kinematic distributions with respect to PDF variations. In the case of the determination of M_{W} from the charged lepton transverse momentum distribution, we observe that the inclusion of this correlation factor yields a strong reduction of the PDF uncertainty, given a sufficiently good control over all the other error sources. This improvement depends on a systematic accounting of the features of the QCD-based PDF model, and it is achieved by relying only on the information available in current PDF sets. While a realistic quantitative estimate requires taking into account the details of the experimental systematics, we argue that, in perspective, the proton PDF uncertainty will not be a bottleneck for precision measurements.

36. Improved determination of the Higgs mass in the MSSM with heavy superpartners.

Author

Bagnaschi E, Vega JP, and Slavich P

Abstract

We present several advances in the effective field theory calculation of the Higgs mass in MSSM scenarios with heavy superparticles. In particular, we compute the dominant two-loop threshold corrections to the quartic Higgs coupling for generic values of the relevant SUSY-breaking parameters, including all contributions controlled by the strong gauge coupling and by the third-family Yukawa couplings. We also study the effects of a representative subset of dimension-six operators in the effective theory valid below the SUSY scale. Our results will allow for an improved determination of the Higgs mass and of the associated theoretical uncertainty.
