Di-photon Higgs Decay in SUSY with CP Violation

Understand

Physical Higgs particles in the Minimal Supersymmetric Standard Model (MSSM) with explicit CP violation are CP mixed states.

• The decay of these Higgs particles can be analysed to study the CP properties of the MSSM.
• In the present work we consider the di-photon channel of the lightest neutral Higgs boson for this purpose.
• Compared to earlier studies on effects of scalar/pseudo-scalar mixing, our analysis also investigates the effect due to Higgs-sfermion-sfermion couplings along with that of mixing.
