QUARTIC ANOMALOUS COUPLINGS IN E-GAMMA COLLIDERS

We study the production of gauge-boson pairs at the next generation of linear e+e- colliders operating in the egamma mode. The processes ega mma --> VV'F (V, V' = W, Z, or gamma and F = e or nu) can give valuabl e information on possible deviations of the quartic vector-boson coupl ings from the Standard Model predictions. We establish the range of th e new couplings that can be explored in these colliders based on a 3si gma effect in the total cross section. We also present several kinemat ical distributions of the final state particles that could manifest th e underlying new dynamics. Our results show that an egamma collider ca n extend considerably the bounds on anomalous interactions coming from oblique radiative corrections and from direct searches in e+e- collid ers.
