Abstract

IDARRAGA, J. P.; MARTINEZ, R.; RODRIGUEZ, J-Alexis  and  POVEDA T., N.. Leptonic decays of the B charged meson and B Xsγ in the Two Higgs Doublet Model type III. Braz. J. Phys. [online]. 2008, vol.38, n.4, pp. 531-535. ISSN 1678-4448.  http://dx.doi.org/10.1590/S0103-97332008000500001.

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 bsγ and the branchings for the meson decays B+l+ν. We examine the limits on the new parameters λbb and M. We take into account the relationship between λtt and λbb coming from the validness of perturbation theory.

Keywords : B Meson decay; 2HDM type III; Charged Higgs mass.
