The di-photon signature of Higgs bosons in GMSB models at the LHC

Abstract

We show how the well studied $\gamma \gamma$ inclusive Higgs signal can be used at the Large Hadron Collider to test Gauge Mediated Supersymmetry Breaking scenarios in which a rather heavy Higgs boson decays into two light neutralinos, the latter yielding two photons and missing (transverse) energy
