Search for gauge-mediated supersymmetry in events with at least one photon and missing transverse momentum in pp collisions at √s=13TeV

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 = 13 TeV was collected with the CMS detector at the CERN LHC and corresponds to an integrated luminosity of 35.9 fb−1. Data are...

The data sample of pp collisions at √s = 13 TeV was collected with the CMS detector at the CERN LHC and corresponds to an integrated luminosity of 35.9 fb−1.

The event selection is optimized for both electroweak (EWK) and strong production SUSY scenarios.
