Tau longitudinal polarization in B -> D tau nu and its role in the search for charged Higgs boson

Abstract

We study the longitudinal polarization of the tau lepton in B -> D tau nu decay. After discussing possible sensitivities of tau decay modes to the tau polarization, we examine the effect of charged Higgs boson on the tau polarization in B -> D tau nu. We find a relation between the decay rate and the tau polarization, and clarify the role of the tau polarization measurement in the search for the charged Higgs boson.
