Discovery limits for Techni-Omega production in $e\gamma$ Collisions

Abstract

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