Search for supersymmetry in final states with photons and missing transverse momentum in pp collisions at 13 TeV using the CMS detector
2019 July 24
Supersymmetry (SUSY) is a theoretically favoured extension of the standard model (SM) since it provides solutions to several open questions. Many models employing gauge mediation (GMSB or GGM) predict the production of events with photons and significant missing transverse momentum. In this paper the results of three new searches for SUSY and a combination analysis are reported. The data sample corresponds to an integrated luminosity of 35.9 fb^−1 collected at a centre-of-mass energy of 13 TeV using the CMS detector at the CERN LHC. The results are used to set cross section limits on gluino, squark and gaugino pair production in either the GMSB or the GGM model framework. The GGM model is favoured for the combination of the search results. By compiling previous results into a single limit setting analysis it is possible to obtain a better sensitivity with respect to individual searches.
