Quartic anomalous couplings in eγ colliders

We study the production of gauge-boson pairs at the next generation of linear e+e- colliders operating in the eγ mode. The processes eγ → VV′F (V,V′ = W,Z, or γ and F = e or ν) can give valuable information on possible deviations of the quartic vector-boson couplings from the Standard Model predictions. We establish the range of the new couplings that can be explored in these colliders based on a 3σ effect in the total cross section. We also present several kinematical distributions of the final state particles that could manifest the underlying new dynamics. Our results show that an eγ collider can extend considerably the bounds on anomalous interactions coming from oblique radiative corrections and from direct searches in e+e- colliders.
