The Pinch Technique And Its Applications To Non-Abelian Gauge Theories (E-Book)
Non-Abelian gauge theories, such as quantum chromodynamics (QCD) or electroweak theory, are best studied with the aid of Green’s functions that are gauge invariant off-shell, but unlike for the photon in quantum electrodynamics, conventional graphical constructions fail. The pinch technique provides a systematic framework for constructing such Green’s functions and has many useful applications.
