Description
In this talk I will discuss the recent status of B to D(*) tau nu decays in the context of two-Higgs-doublet models. The BaBar collaboration has reported an excess in semileptonic b -> c tau nu transitions that has gathered recent interest as a possible signature of new physics. I will discuss the sensitivity of this decays to charged Higgs boson contributions, taking into account the constraints from other semileptonic and leptonic meson decays in which the charged Higgs would enter at the same level.
