Description
Recently the one-loop perturbative QCD correction to the longitudinal polarization of tau lepton in semileptonic B decays has been found. Its smallness suggests that the higher order perturbative corrections are generally insignificant as far as the polarization is concerned. Prompted by the experimental need, I give here the polarization with respect to the W boson direction in Born approximation. (author)
