Distinguishing Higgs models in H^+ -> tau^+ nu /t b-bar at large tan beta

Abstract

We present an experimental and theoretical analysis of the ratio of branching ratios R=BR(H^+ -> tau^+ nu)/BR(H^+ -> t b-bar) of charged Higgs boson decays as a discriminant quantity between supersymmetric and non-supersymmetric models.
