Abstract
We examine the claim that the effective action of four-dimensional SU(2)L gauge theory at high and low temperature contains a three-dimensional Chern-Simons term which has the chemical potential for baryon number as its coefficent. The four-dimensional theory has a two-dimensional analogue in which exact calculations can be performed. These calculations demonstrate that the existence of the Chern-Simons term in four dimensions may be rather subtle.
