Anomalous $Z^{\prime }$ effects in the WW channel at $LC2000$

Abstract

We consider the virtual signals of a $Z^{\prime }$ of very general type in the process $e^{+}{e}^{-}\to W^{+}{W}^{-}$ at a future linear $e^{+}{e}^{-}$ collider of 2000 GeV c.m. energy ($LC2000$). We show that possible deviations from the SM predictions in this channel are related to similar deviations in the purely leptonic one in a way that is only characteristic of this $Z^{\prime }$ model, and not in general of possible competitor models with anomalous gauge couplings.
