Effects of charged Higgs boson and QCD corrections in $\bar{B}\to D\tau {\bar{\nu }}_{\tau }$

Tsutomu Miki, Takahiro Miura, Minoru Tanaka

We study effects of charged Higgs boson exchange in $\bar{B}\to D\tau {\bar{\nu }}_{\tau }$. The Yukawa couplings of Model II of two-Higgs-doublet model, which has the same Yukawa couplings as MSS…
