Abstract

We consider the Two Higgs Doublet Model (2HDM) of type III which leads to Flavour Changing Neutral Currents (FCNC) at tree level. In the framework of this model we calculate the NLO contribution for b->s γand the branchings for the meson decays B⁺ -> l⁺ ν. We examine the limits on the new parameters λ_bb and M_H^±. We take into account the relationship between λ_tt and λ_bb coming from the validness of perturbation theory.
