One-loop correction to the $\gamma WW$ vertex in the $e^{-}\gamma$ collider

Abstract

We apply the pinch technique , which is a method to construct the gauge independent off-shell Green's functions, to the process $e^{-}\gamma \to W^{-}\nu$ to study the effects of radiative corrections to $WW\gamma$ three gauge boson vertex. The one-loop contributions to the anomalous gauge boson couplings are estimated in the standard model.
