Finite width effects ine + e −→Z 0 Z 0

Abstract

The total cross section for the processe + e −→Z 0 Z 0 followed by the subsequent decay of theZ 0-bosons is calculated within the electroweak standard model including one-loop radiative corrections. The effects of the finite width are described in detail. Numerically they are of the order of 10% and thus comparable to the radiative corrections.
