Some results on the distinction of Higgs boson models

Abstract

We present results on the analysis of the ratio of branching ratios $R=BR(H->b\bar{b})/BR(H->{\tau }^{+}{\tau }^{-})$ of Higgs boson decays as a discriminant quantity between supersymmetric and non-supersymmetric models. A detailed analysis in the effective Lagrangian approach shows how one could discriminate between models at the Large Hadron Collider and the $e^{+}{e}^{-}$ Linear Collider at 500 GeV center of mass energy.
