Anomalous Gauge Boson Couplings in the e^+ e^- -> ZZ Process

Abstract

We discuss experimental aspects related to the ${\mathrm{e}}^{+}{\mathrm{e}}^{-}\to \mathrm{ZZ}$ process and to the search for anomalous ZZV couplings (V$=\mathrm{Z},\gamma$) at LEP2 and future ${\mathrm{e}}^{+}{\mathrm{e}}^{-}$ colliders. We present two possible approaches for a realistic study of the reaction and discuss the differences between them. We find that the optimal method to study double Z resonant production and to quantify the presence of anomalous couplings requires the use of a complete four-fermion final-state calculation.
