LHCHWG MSSM ROOT files

This Zenodo record stores the ROOT files generated by the MSSM subgroup of the LHC Higgs Working Group (LHCHWG) to publicly distribute the physics information required to properly interpret LHC measurements and searches in the context of a variety of MSSM scenarios.

The scenarios contained in this release are:

• the six scenarios presented in Eur.Phys.J.C 79 (2019) 7, 617 (1808.07542 [hep-ph]);

• the two heavy-SUSY/low-tb scenarios published in Eur.Phys.J.C 79 (2019) 3, 279 (1901.05933 [hep-ph]);

• the three negative mu scenarios presented in Eur.Phys.J.C 80

• (2020) 10, 916 (2005.14536 [hep-ph];

• the hMSSM scenario introduced in JHEP 10 (2013) 028 (1304.1787 [hep-ph]).

For each scenario, three ROOT files are provided, corresponding to cross-sections computed at 8, 13 and 14 TeV.

For more information on the tools used to generate the predictions contained in the ROOT files, and on the structure of the ROOT files itself, we refer to the working group note LHCHWG-2021-001 (https://cds.cern.ch/record/2791954/).

Changelog

04/07/2022

• Replaced all the ROOT files corresponding to the scenarios where HDECAY is used (mh125,mh125lc,mh125ls,mh125muneg_1,mh125muneg_2,mh125muneg_3,mh123align) with new versions generated with an update version of HDECAY-6.61 that resolve an issue with the genuine SUSY-QCD contributions to the  \(b\bar{b}\)  decay channels introduced in the original 6.61 release.

07/03/2022

• Fixed various issues in the ROOT files of the MHH125 scenario

02/12/2021

• First release on Zenodo;
• Updated the hMSSM ROOT file to the same setup used for the other scenarios (latest version of SusHi; PDF4LHC15 recommendations; \(b\bar{b}\) cross-sections from the matched results provided by the bbH WG; inclusion of reference SM histograms);
• Added the cross sections for the VBF, Higgsstrahlung and ttH production processes for the three neutral Higgses and for the SM reference case;
• Added mixing information of the neutral Higgs sector;
• Added the trilinear self-coupling of the SM-like Higgs, and of a SM Higgs with the same (the latter at tree level and including the \(m_t^4\) term);
• Cleaned-up and reorganized the histograms with a more consistent naming;
• Removed the decay \(H^{\pm} \to us\) due to theoretical issues;
• Update to the HDECAY version 6.61  (\(\Delta_b\) with electroweak 2-loop corrections proportional to \(\alpha_1\)and \(\alpha_2\); \(m_t^4\)term in the hMSSM trilinear self-coupling);
