Electroweak pinch technique to all orders
The generalization of the pinch technique to all orders in the electroweak sector of the Standard Model within the class of the renormalizable ’t Hooft gauges, is presented. In particular, both the all-order PT gauge-boson– and scalar–fermions vertices, as well as the diagonal and mixed gauge-boson and scalar self-energies are explicitly constructed. This is achieved through the generalization ...
متن کاملThe Pinch Technique to All Orders
The generalization of the pinch technique to all orders in perturbation theory is presented. The effective Green’s functions constructed with this procedure are singled out in a unique way through the full exploitation of the underlying Becchi-Rouet-Stora-Tyutin symmetry. A simple all-order correspondence between the pinch technique and the background field method in the Feynman gauge is establ...
متن کاملPinch technique self - energies and vertices to all orders in perturbation theory
Daniele Binosi and Joannis Papavassiliou Departamento de F́ısica Teórica and IFIC, Centro Mixto, Universidad de Valencia-CSIC, E-46100, Burjassot, Valencia, Spain Abstract The all-order construction of the pinch technique gluon self-energy and quark-gluon vertex is presented in detail within the class of linear covariant gauges. The main ingredients in our analysis are the identification of a sp...
متن کاملIntroduction to the Pinch Technique
These notes are a short introduction to the pinch technique. We present the oneloop calculations for basic QCD Green’s functions. The equivalence between the pinch technique and the background field method is explicitly shown at the one-loop level. We review the absorptive pinch technique in the last sections. These lectures are a compilation of relevant papers on this subject and are prepared ...
