Description
A search for gauge-mediated supersymmetry (SUSY) in final states with
photons and large missing transverse momentum is presented. The data
sample of pp collisions at √{ s } = 13TeV was collected with the
CMS detector at the CERN LHC and corresponds to an integrated luminosity
of 35.9 fb-1. Data are compared with models in which the
lightest neutralino has bino- or wino-like components, resulting in
decays to photons and gravitinos, where the gravitinos escape detection.
The event selection is optimized for both electroweak (EWK) and strong
production SUSY scenarios. The observed data are consistent with
standard model predictions, and limits are set in the context of a
general gauge mediation model in which gaugino masses up to 980 GeV are
excluded at 95% confidence level. Gaugino masses below 780 and 950 GeV
are excluded in two simplified models with EWK production of
mass-degenerate charginos and neutralinos. Stringent limits are set on
simplified models based on gluino and squark pair production, excluding
gluino (squark) masses up to 2100 (1750) GeV depending on the
assumptions made for the decay modes and intermediate particle masses.
This analysis sets the highest mass limits to date in the studied EWK
models, and in the considered strong production models when the mass
difference between the gauginos and the squarks or gluinos is small.
