Query: B physics and Extended Higgs sectors (Tauonic B decays and two Higgs
  doublet models)   Recent experimental results on exclusive semi-tauonic B meson decays show
sizable deviations from the standard model prediction, while the recent result
on pure-tauonic decay reduces the deviation from the prediction. These results
suggest an indirect evidence of new physics in which the structure of the
relevant weak charged interaction may differ from that of the standard model.
We study these tauonic B decays in the context of extensions of the Higgs
sector. As a result, we find that two Higgs doublet models without tree-level
FCNC are unlikely to explain the present experimental data while those allowing
FCNC are consistent with the data.
