Abstract

A study of the semi-analytical approach to four-fermion production in e+e annihilation is presented. We classify all possible four-fermion final states and present results of new calculations for the ‘basic’ processes with the WW, ZZ, and ZH off-shell production together with some examples of ‘background’ processes. The Initial State Radiative corrections are included for the basic processes. Several numerical examples are given in the energy range from LEP 2 up to s = 1 TeV.
