Z Anomalous Couplings and the Polarization Asymmetry in $\gamma e\to Ze$

Abstract

We extend our previous analysis of the sensitivity of the energy dependence of the polarization asymmetry in $\gamma e\to W\nu$ to the possible existence of anomalous trilinear gauge couplings to the $\gamma e\to Ze$ case. We find that by combining the constraints imposed by both the energy dependence of the total cross section and polarization asymmetry, strong limits on the anomalous $\gamma ZZ$ couplings are obtainable at the Next Linear Collider. Further constraints obtained from a consideration of the angular distribution are briefly discussed.
