Abstract

Evaluation of anomalous couplings in the γγ→ W⁺W^- process needs to calculate the cross section σ(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 L₀, \cal L_c, \cal L₀ are analyzed in high-energy region. Influence of high order effects is studed in dependences of σ(W⁺W^-) on anomalous constants and contour plots with statistical error 2δ.
