The pinch technique approach to gauge-independent n-point functions
N. J. Watson
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-…

Effective Charges in Non-Abelian Gauge Theories
N. J. Watson
The question of the definition of effective charges for non-abelian gauge theories is discussed, focusing in particular on both the pinch technique and background field method appr…
