Light Chargino Effects onto H -> gamma gamma in the MSSM

Abstract

We analyse the implications of light charginos on the Higgs boson signal strength via gluon-gluon fusion and di-photon decay in the Minimal Supersymmetric Standard Model (MSSM) at the Large Hadron Collider (LHC). We show that enhancements are possible with a rate up to 25%. We also prove that they are possible for a high scale constrained version of the MSSM with non-universal Higgs and gaugino masses. In contrast, effects due to light charged Higgs bosons, that we also have investigated, are generically negligible in the γγdecay, though they may affect the b \bar b rate, hence the total width.
