Abstract

Higgs particles in SUSY theories receive large radiative corrections in 
the fermion couplings that must be taken into account in phenomenological 
analyses. We present results on the analysis of the ratios of branching 
ratios R=BR(H -> b b-bar)/BR(H -> tau^+ tau^-) and R=BR(H^+ -> tau 
nu)/BR(H^+ -> t b-bar) of neutral and charged Higgs boson decays as 
discriminant quantities between supersymmetric and non-supersymmetric 
models. A detailed analysis in the effective Lagrangian approach has been 
done. For the ratio of charged Higgs boson decays, simulation of 
measurements of this quantity through the analysis of the charged Higgs 
production process gb-> t b H^+ and relative backgrounds in the two above 
decay channels has been performed in the context of ATLAS.
