摘要：
We calculate the O(alpha(s)) radiative corrections to polarized top quark decay into a charged Higgs boson and a massive bottom quark in two variants of the two-Higgs-doublet model. The radiative corrections to the polarization asymmetry of the decay may become as large as 25%. We provide analytical formulae for the unpolarized and polarized rates for m(b)not equal 0 and for m(b)=0. For m(b)=0 our closed-form expressions for the unpolarized and polarized rates become rather compact.
