An alternative model for the electroweak symmetry breaking sector and its signature in future e-gamma colliders

We perform a preliminary study of the deviations from the Standard Model prediction for the cross section for the process $e γ\rightarrow ν_e W γ$. We work in the context of a higgsless chiral lagrangian model that includes an extra vector resonance $V$ and an anomalous $γW V$ coupling. We find that this cross section can provide interesting constraints on the free parameters of the model once it is measured in future $e γ$ colliders.
