Abstract

A combination of four searches for new physics involving signatures withat least one photon and large missing transverse momentum, motivated bygeneralized models of gauge-mediated supersymmetry (SUSY) breaking, ispresented. All searches make use of proton-proton collision data at roots = 13 TeV, which were recorded with the CMS detector at the LHC in2016, and correspond to an integrated luminosity of 35.9 fb(-1).Signatures with at least one photon and large missing transversemomentum are categorized into events with two isolated photons, eventswith a lepton and a photon, events with additional jets, and events withat least one high-energy photon. No excess of events is observed beyondexpectations from standard model processes, and limits are set in thecontext of gauge-mediated SUSY. Compared to the individual searches, thecombination extends the sensitivity to gauge-mediated SUSY in bothelectroweak and strong production scenarios by up to 100GeV inneutralino and chargino masses, and yields the first CMS resultcombining various SUSY searches in events with photons at root s = 13TeV.
