Abstract

We apply the pinch technique , which is a method to construct the gauge independent off-shell Green's functions, to the process $e^-\gamma \rightarrow W^-\nu$ 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.
