Discovery Limits for Techni-Omega Production in $eγ$ Collisions

Abstract

In a strongly-interacting electroweak sector with an isosinglet vector state, such as the techni-omega, $ω_T$, the direct $ω_T Z γ$ coupling implies that an $ω_T$ can be produced by $Z γ$ fusion in $eγ$ collisions. This is a unique feature for high energy $e^+e^-$ or $e^-e^-$ colliders operating in an $eγ$ mode. We consider the processes $e^- γ\to e^- Zγ$ and $e^- γ\to e^- W^+ W^-Z$, both of which proceed via an intermediate $ω_T$. We find that at a 1.5 TeV $e^+e^-$ linear collider operating in an $eγ$ mode with an integrated luminosity of 200 fb$^{-1}$, an $ω_T$ can be discovered for a broad range of masses and widths.
