Description
Semileptonic and leptonic B meson decays involving a heavy $\tau$ lepton are sensitive to new physics scenarios with an extended Higgs sector, such as the type-II two-Higgs-doublet model. Decays that have been studied at Belle include $B\to D^{(*)}\tau\nu$ , $B\to \tau\nu$ and $B\to \pi\tau\nu$. In this talk we report new and updated results for these modes, based on the large data sample accumulated by the Belle experiment at the KEKB asymmetric-energy e+e− collider at KEK, Japan.
