摘要: We calculate the O(alpha_s) radiative corrections to three spin independent and five dependent structure functions that describe angular decay distribution in of a polarized top quark into W-boson (followed by W^{+} -> l^{+} + nu_l or anti-q q bottom quark. The is described cascade fashion, i.e. t(uparrow) X_b analyzed rest system while subsequent (or q) W frame. present our results for eight integrated analytical form keeping mass finite. In limit m_b 0 function expressions reduce rather compact forms.
