Anomalous Higgs Couplings at an $e γ$ Collider

Abstract

We examine the sensitivity of $e γ$ colliders (based on $e^+ e^-$ linear colliders of c.m. energy 500 GeV) to the anomalous couplings of the Higgs to W-bosons via the process $e^- γ\longrightarrow νW H$. This has the advantage over $e^+ e^-$ collider in being able to dissociate WWH vertex from ZZH. We are able to construct several dynamical variables which may be used to constrain vrious couplings in the WWH vertex.
