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 \gamma\gamma decay, though they may affect the b \bar b rate, hence the total width.
