Abstract
The analytic formulae for the partial decay widthW +→\(f_1 \bar f_2 \) are presented including the 1-loop electroweak and QCD corrections for arbitrary masses of the fermions. Numerical results are discussed for the physically interesting cases\(W^ + \to t\bar b\) and for the decay into a heavy leptonl + and a neutrino of a fourth fermion generation. Also the results for the totalW width and the partial width into light fermion pairs are listed.
