Search for stealth SUSY in final states with two photons, jets, and low missing transverse momentum

The results of a search for stealth supersymmetry (SUSY) in final states with two photons, jets, and low missing transverse momentum are reported. The study is based on a $138~\mathrm{fb}^{-1}$ sample of proton-proton collisions collected at 13 TeV with the CMS detector. Many models of new physics predict the production of events with jets and electroweak gauge bosons, with little or no missing transverse momentum. Examples include stealth models of SUSY, which predict a hidden sector at the electroweak energy scale for which SUSY is an approximately unbroken symmetry. The results are interpreted in the context of simplified stealth models with gluino and squark pair production. The observed data are consistent with the Standard Model prediction, and gluino (squark) masses of up to 2.1 (1.85)~TeV are excluded.
