On the Non-Renormalization Properties of Gauge Theories with Chern-Simons Terms

Considering three-dimensional Chern-Simons theory, either coupled to matter or with a Yang-Mills term, we show the validity of a trace identity, playing the role of a local form of the Callan-Symanzik equation, in all orders of perturbation theory. From this we deduce the vanishing of the \beta-function associated to the... Show more
