Abstract
A combination of four searches for new physics involving signatures with atleast 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 $\sqrt{s}=$ 13 TeV, which were recorded with the CMS detector at the LHC in 2016, andcorrespond to an integrated luminosity of 35.9 fb$^{-1}$. Signatures with atleast one photon and large missing transverse momentum are categorized intoevents with two isolated photons, events with a lepton and a photon, eventswith additional jets, and events with at least one high-energy photon. Noexcess of events is observed beyond expectations from standard model processes,and limits are set in the context of gauge-mediated SUSY. Compared to theindividual searches, the combination extends the sensitivity to gauge-mediatedSUSY in both electroweak and strong production scenarios by up to 100 GeV inneutralino and chargino masses, and yields the first CMS result combiningvarious SUSY searches in events with photons at $\sqrt{s} =$ 13 TeV.
