INDUCED CHERN-SIMONS TERM AT HIGH-TEMPERATURE IN INTRINSIC REGULARIZATION

By perturbative calculations of the high temperature ground-state axia l current in intrinsic regularization, an anomalous Chern-Simons topol ogical mass term is induced in the three-dimensional effective action. The anomaly in three dimensions appears just in the ground-state curr ent rather than in the divergence of ground-state current. In the abel ian case, the contribution comes only from the vacuum polarization gra ph, whereas in the nonabclian case, contributions come from the vacuum polarization graph and the two triangle graphs.
