High Order QED Effects on Anomalous Quartic Boson Vertices in -Colliders
I.B. Marfin, V.A. Mossolov, and T.V. Shishkina

At linear colliders with centre of mass energies running to 1 TeV there is a hope for the detection of deviations from SM predictions. The production of two and three electroweak gauge bosons in the high-energy collisions allows to check anomalous quartic gauge boson couplings. The influence of three possible anomalous couplings on the cross sections of W⁺W^- productions has been investigated at the TESLA kinematics (~1TeV). There is the significant discrimination between various anomalous contributions. The main contribution of high order electroweak effects is considered.
Key words: linear collider, W⁺W^- pair production, anomalous quartic boson couplings
