Abstract: Results of a search for supersymmetry are presented using events with a photon, an electron or muon, and large missing transverse momentum. The analysis is based on a data sample corresponding to an integrated luminosity of 35.9 fb$^{-1}$ of proton-proton collisions at $\sqrt{s} = $ 13 TeV, produced by the CERN LHC and collected with the CMS detector in 2016. Models of supersymmetry with gauge-mediated supersymmetry breaking yield events with photons in the final state as well as electroweak gauge bosons decaying to leptons. Searches for events with both a photon and a lepton are sensitive probes of these models. No excess of events is observed beyond expectations from standard model processes. The results of the search are interpreted in the context of simplified models inspired by gauge-mediated supersymmetry breaking. These models are used to derive upper limits on the production cross sections of supersymmetric processes and set bounds on masses of supersymmetric particles.
