Dimensional Reduction for Fermions
Abstract
Description
We generalize the concept of dimensional reduction to operators involving fermion fields in high temperature field theories. It is found that the ultraviolet behavior of the running coupling constant plays a crucial role. The general concept is illustrated explicitly in the Gross-Neveu model.
