Search for Anomalous Couplings at $e\gamma$ Colliders

Abstract

We consider the possibility of observing deviations from the Standard Model gauge-boson self-couplings at future $e\gamma$ colliders. We concentrate on the process $e^{-}\gamma \to \nu W^{-}Z$, which is particularly sensitive to the parity violating coupling $g_5^Z$ at high energies. We find that a 2~TeV $e^{+}{e}^{-}$ collider operating in the $e^{-}\gamma$ mode could reach a sensitivity of order $5\times 10^{-3}$ to $g_5^Z$.
