A cross-section calculation for the Standard Model reaction e+e−→(Z0Z0)→f1f1ˉf2f2ˉ including the effects of the finite Z0~width and initial state radiative corrections is presented. The angular phase space integrations are performed analytically, leaving the invariant masses for numerical integration. Semi-analytical and numerical results in the energy range s=150GeV to 1TeV are reported.
