Abstract
We consider the renormalization of the twist two, dimension four gauge invariant operator O μν (1) = − F μσ F νσ − g μν L 0. By using the general theory of renormalization of gauge invariant operators, we find the gauge noninvariant operator O (2) with which it mixes. We construct a finite combination of O (1) and O (2) and show that it is an acceptable energy momentum tensor for gauge theories. We compare our energy momentum tensor with that constructed by Freedman, Muzinich, and Weinberg.
