Search for supersymmetry in final states with at least one photon and MET in pp collisions at sqrt(s)=13 TeV

A search for electroweak production of gauginos is presented using the first LHC Run~II data at a center-of-mass energy of 13~TeV. The used data set has been recorded with the CMS detector and corresponds to an integrated luminosity of $2.3\,\text{fb}^\text{$-$1}$. In gauge-mediated supersymmetry breaking (GMSB) models the gauginos can decay to photons, or other standard model bosons, and gravitinos. The final state considered in this search is characterized by photons and missing transverse energy. Since in electroweak production scenarios the expected hadronic activity is low compared to strong production, no jet requirements are used. Additionally, gluino pair production models are considered, where the analysis does not lose sensitivity in scenarios with compressed mass spectra. The observed data are in agreement with the standard model prediction and limits are set on different models of GMSB.
