Universal regularizations
Description
Rules of a 'universal' ulrtaviolet regularization (different from the dimensional one) aimed at preserving internal symmetries in nonanomalous situations are formulated. The regularization is tantamount to the integration (with a certain weight) of Feynman graphs over 'soft masses' introduced specially into graphs and arising as a result of 'enlarging' the loop momenta. One-loop examples related to abelian and nonabelian gauge theories are considered. It is shown that the 'universal' regularization is indeed in accordance with corresponding symmetries. Mechanism of the axial anomaly is discussed in terms of the 'universal' regularization
