We apply the pinch technique , which is a method to construct the gauge independent off-shell Green's functions, to the process $e^-γ\rightarrow W^-ν$ 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.
We investigate the spin structure function $g_2 (x, Q^2 )$ in the framework of the operator product expansion and the renormalization group. The twist-3 operators appearing in QCD are examined and their relations are studied. It is noted that operators proportional to equation of motion appear in the operator mixing through renormalization, which can be studied from the relevant Green's functions. We also note that the coefficient functions can be properly fixed after the choice of independent operators.
