Discovery limits for techni-omega production in e γ collisions -: art. no. 095006

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 -->e(-)Z gamma and e(-)gamma-->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 ey mode with an integrated luminosity of 200 fb(-1), an omega(T) can be discovered for a broad range of masses and widths.
