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/). For more information on the MSSM subgroup, please see the Twiki page at https://twiki.cern.ch/twiki/bin/view/LHCPhysics/LHCHWGMSSMNeutral.
