摘要：

We study perturbative renormalization of D = 3 Chern-Simons gauge theory coupled to scalar and fermionic matter. We show that in the non-Abelian case the coefficient of the Chern-Simons term has infinite renormalization and that both the matter and the non-Abelian guage fields acquire nonvanishing anomalous dimensions at the two-loop level. However, the two-loop beta-function of the guage coupling always vanishes, indicating that scale and conformal invariance survive quantization and infinite renormalization.
