An efficient method for calculating polarized matrix elements of the
four fermion reactions e+e“ —t 4 / and corresponding hard bremsstrahlung
reactions with non-zero fermion masses is discussed. The numerical results
for the total cross sections and some differential cross sections of e+e“ —t
u d ^P n and e+e“ —t udg^vllA are given. The dependence on the fermion
masses is illustrated by comparing the hard bremsstrahlung corrections to
different semi-leptonic channels.
