Abstract

We apply the pinch technique , which is a method to construct the gauge independent off-shell Green's functions, to the process e-γ→ W-ν to study the effects of radiative corrections to WWγ three gauge boson vertex. The one-loop contributions to the anomalous gauge boson couplings are estimated in the standard model.
