Radiative corrections to helicity amplitudes forW-pair production ine + e?-annihilation

Radiative corrections toW pair production ine ⁺ e^?-annihilation are investigated. In an earlier work we discussed only the weak corrections to this process. Here we present the complete calculation including QED corrections. Full agreement with other authors is achieved. We use the helicity formalism for the projection of theS-matrix into invariant amplitudes and study the dependence of cross sections on the Higgs and top masses. Effects due to the choice of the renormalization scheme are considered.
