Abstract

We update the flavor-violating constraints on the charged Higgs sector of the 2-Higgs Doublet Model Type-III (2HDM-III), using a four-zero texture in the Yukawa matrices. We give a generic Lagrangian of the 2HDM-III. In order to show the relevance of the off-diagonal terms of such a texture, we utilize the main constraints from B-physics, μ - e universality in τ decays and the radiative decay Zb ‾b presented recently in arXiv:1212.6818 [hep-ph]. In particular, we show that the H - c ‾b coupling can be very large and very different with respect to 2HDMs with a flavor discrete symmetry (i.e., Z2). We also discuss the possible enhancements of the vertices H± W± V (V=Z, γ) that arise at one-loop level.
