Description
The Belle II experiment aims to record 50 ab$^{-1}$ data with the high
luminosity to be provided by the SuperKEKB energy-asymmetric $e^+e^-$
collider. The anticipated high statistics data enables us to perform
studies of $B$ decays involving $\tau$ leptons such as
$B^+ \to \tau^+ \nu_{\tau}$ and $B \to D^{(*)} \tau^+ \nu_{\tau}$ modes.
The precise measurements of branching fraction as well as the $\tau$
lepton polarization in these $B$ decays provide a very sensitive indirect
search for a charged Higgs boson. Belle IIs's sensitivity for the charged
Higgs is complementary to direct searches at ATLAS and CMS.
