QCD corrections to the decay t→Wb in dimensional regularization
Description
A calculation of first order QCD correction to the decay of the top quark into W boson and b quark is presented. Both ultraviolet and infrared divergences are regularized using dimensional regularization, i.e., without introducing any gluon mass. (orig.)
