2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/42609We present results on the analysis of the ratio of branching ratios $R=BR(H->b\bar{b})/BR(H->τ^+τ^-)$ 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.LaTeX, 5 pages, 3 figures, Based on talk given at Second Workshop of the Extended ECFA/DESY Study, Saint Malo, April 12-15, 2002High Energy Physics - Phenomenologytext
