Abstract
A search for supersymmetry (SUSY) is presented where at least one Higgsboson is produced and decays to two photons in the decay chains ofpair-produced SUSY particles. Two analysis strategies are pursued: onefocused on strong SUSY production and the other focused on electroweakSUSY production. The presence of charged leptons, additional Higgs bosoncandidates, and various kinematic variables are used to categorizeevents into search regions that are sensitive to different SUSYscenarios. The results are based on data from proton-proton collisionsat the Large Hadron Collider at a center-of-mass energy of 13 TeVcollected by the CMS experiment, corresponding to an integratedluminosity of 77.5 fb(-1). No statistically significant excess of eventsis observed relative to the standard model expectations. We excludebottom squark pair production for bottom squark masses below 530 GeV anda lightest neutralino mass of 1 GeV; wino-like chargino-neutralinoproduction in gauge-mediated SUSY breaking (GMSB) for chargino andneutralino masses below 235 GeV with a gravitino mass of 1 GeV; andhiggsino-like chargino-neutralino production in GMSB, where theneutralino decays exclusively to a Higgs boson and a gravitino forneutralino masses below 290 GeV.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
