The pinch technique (PT) is an algorithm for the rearrangement of contributions to conventional, gauge-dependent n-point functions in gauge theories to obtain a formulation of one-loop perturbation theory in terms of " effective " n-point functions which, principle among many other desirable properties, are individually entirely independent of the… CONTINUE READING
