Scientific paper

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 ${\cal L}_0$, ${\cal L}_c$, $\tilde{{\cal L}}_0$ 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 $2\delta$.
