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


Abstract in English

The production of two and three electroweak gauge bosons in the high-energy $gammagamma$ 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.
