摘要：

We calculate Higgs decay rates into gamma gamma and Z gamma in the minimal supersymmetric Standard Model and (B-L) supersymmetric Standard Model by allowing for contributions from light staus ((tau) over tildes) and charginos ((chi) over tilde (+/-)s). We show that sizable departures are possible from the Standard Model predictions for the 125 GeV state and that they are testable during Run 2 at the Large Hadron Collider. Furthermore, we illustrate how a second light scalar Higgs signal in either or both of these decay modes can be accessed at the CERN machine rather promptly within the (B-L) supersymmetric Standard Model, a possibility instead precluded to the minimal supersymmetric Standard Model, owing to the much larger mass of its heavy scalar state.
