Abstract

The fermion mass effects in e(+)e(-) --> 4f and in the corresponding bremsstrahlung reactions in the presence of realistic cuts are studied. It is shown that, for some four-fermion final states, the mass effects become sizable to the extent that the may affect the accuracy of theoretical predictions which is required to be better than 1%.
