Anomalous quartic boson couplings via gamma gamma --> WW and gamma gamma --> WWZ at the TESLA kinematics

Abstract

The production of two and three electroweak gauge bosons in the high-energy $\gamma \gamma$ collisions gives the well opportunity to probe anomalous quartic gauge boson couplings. The influence of five possible anomalous couplings on the cross sections for $W^{+}{W}^{-}$, $W^{+}{W}^{-}\gamma$, $W^{+}{W}^{-}Z$ productions has been investigated at the TESLA kinematics ($\sqrt{S}\sim 1$ TeV). There are the reasonable discriminations between various anomalous contributions.
