Derivative expansion of quadratic operators in a general 't Hooft gauge

Research output: Contribution to journalArticle

Abstract

A derivative expansion technique is developed to compute functional determinants of quadratic operators, nondiagonal in spacetime indices. These kinds of operators arise in general 't Hooft gauge fixed Lagrangians. Elaborate applications of the developed derivative expansion are presented.
