摘要：
QCD corrections to the double differential lepton spectrum from the decay of a polarized top quark are calculated. It is shown that the factorization into energy-dependent and angular-dependent parts holds true also for the QCD corrected spectrum to a high degree of accuracy. A compact formula is given for the remaining small corrections.
