Abstract

The results of a search for stealth supersymmetry in final states with two photons and jets, targeting a phase space region with low missing transverse momentum ((Formula presented)), are reported. The study is based on a sample of proton-proton collisions at (Formula presented) collected by the CMS experiment, corresponding to an integrated luminosity of (Formula presented). As LHC results continue to constrain the parameter space of the minimal supersymmetric standard model, the low (Formula presented) regime is increasingly valuable to explore. To estimate the backgrounds due to standard model processes in such events, we apply corrections derived from simulation to an estimate based on a control selection in data. The results are interpreted in the context of simplified stealth supersymmetry models with gluino and squark pair production. The observed data are consistent with the standard model predictions, and gluino (squark) masses of up to 2150 (1850) GeV are excluded at the 95% confidence level.
