Triple Vector Boson Processes in $\gamma \gamma$ Colliders

Abstract

We study the production of three gauge bosons at the next generation of linear $e^{+}{e}^{-}$ colliders operating in the $\gamma \gamma$ mode. The processes $\gamma \gamma \to W^{+}{W}^{-}V$ ($V=Z^0$, or $\gamma$) can provide direct information about the quartic gauge-boson couplings. We analyze the total cross section as well as several dynamical distributions of the final state particles including the effect of kinematical cuts. We find out that a linear $e^{+}{e}^{-}$ machine operating in the $\gamma \gamma$ mode will produce 5--10 times more three-gauge-boson states compared to the standard $e^{+}{e}^{-}$ mode at high energies.
