Descripción
A search for physics beyond the standard model in final states with at
least one photon, large transverse momentum imbalance, and large total
transverse event activity is presented. Such topologies can be produced
in gauge-mediated supersymmetry models in which pair-produced gluinos or
squarks decay to photons and gravitinos via short-lived neutralinos. The
data sample corresponds to an integrated luminosity of 35.9
fb-1 of proton-proton collisions at √{s}=13 TeV recorded
by the CMS experiment at the LHC in 2016. No significant excess of
events above the expected standard model background is observed. The
data are interpreted in simplified models of gluino and squark pair
production, in which gluinos or squarks decay via neutralinos to
photons. Gluino masses of up to 1.50-2.00 TeV and squark masses up to
1.30-1.65 TeV are excluded at 95% confidence level, depending on the
neutralino mass and branching fraction.
