Nonrenormalization Theorem for Gauge Coupling in 2+1D

arXiv:hep-th/9401053 · doi:10.1142/S0217732394001787

Abstract

We prove that $\be$-function of the gauge coupling in gauge theory coupled to any renormalizable system of spinor and scalar fields is zero. This result holds both when the gauge field action is the Chern-Simons action and when it is the topologically massive action.
