Results are reported of a search for supersymmetry in final states with photons
and missing transverse momentum in proton-proton collisions at the LHC. The data sample
corresponds to an integrated luminosity of 35.9 fb−1
collected at a center-of-mass energy
of 13 TeV using the CMS detector. The results are interpreted in the context of models of
gauge-mediated supersymmetry breaking. Production cross section limits are set on gluino
and squark pair production in this framework. Gluino masses below 1.86 TeV and squark
masses below 1.59 TeV are excluded at 95% confidence level
