摘要：

We compute the supersymmetric QCD corrections to the decay distribution of polarized top quarks for the semileptonic decay mode t(up arrow) --> bl(+)nu(l). As a byproduct, we reinvestigate the SUSY-QCD corrections to the total decay width Gamma(t --> W(+)b) and resolve a discrepancy between two previous results in the literature.
