Universal regularizations. IV. Compensations of diagrams in Ward identities
O. I. Zavialov, A. M. Malokostov Steklov Mathematical Institute, Russian Academy of Sciences
Abstract:
On the diagram level we describe the mechanism of compensations in Ward identities for non-Abelian gauge theories. The description of this mechanism allows one to analyze the non-Lagrangian regularizations. We propose the version of regularization from the class of “universal” regularizations which keeps the gauge invariance in one-loop approximation and in two-loop approximation, at least for polarization operator.
