Covariant Mass and Geometrical setup in Euclidean gauge theories

Abstract

A nonlocal mass operator can be consistently set in local form through the introduction of a set of additional fields with geometrical appropriated properties. A local and polynomial gauge invariant action is thus identified. Equations compatible with the study of renormalization, from the algebraic point of view, are presented in the Landau Gauge.
