Abstract

A cross-section calculation for the Standard Model reaction e⁺e^- → (Z⁰Z⁰) → f₁f₁f₂f₂ 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)=150 GeV to 1 TeV are reported.
