Probing anomalous Higgs couplings at an eγ collider using unpolarised beams

We examine the sensitivity of eγ colliders (based on e + e − linear colliders of c.m. energy 500 GeV) to the anomalous couplings of the Higgs to W-boson via the process e − γ → νWH. 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 the various couplings in the WWH vertex.
