Contribution of the main radiative corrections to anomalous quartic constants in process gamma-gamma-->WW

Abstract

Evaluation of anomalous couplings in the $\gamma \gamma \to W^{+}{W}^{-}$ process needs to calculate the cross section $\sigma (W^{+}{W}^{-})$ with a high precision. Therefore one has to consider the main contribution of high order effects. In this paper contributions of anomalous quartic boson interaction given by ${\mathcal{L}}_0$, ${\mathcal{L}}_c$, ${\tilde{\mathcal{L}}}_0$ are analyzed in high-energy region. Influence of high order effects is studed in dependences of $\sigma (W^{+}{W}^{-})$ on anomalous constants and contour plots with statistical error $2\delta$.
