Topological Mass vs. Dynamical Mass: Novelty in (2+1)-dimensional Space-Time

High Energy Physics - Theory 2007-05-23 v1

Abstract

The restriction of space-time dimensions to "2+1" leads us to a novel quantum field theory which has the Chern-Simons term in its action. This term changes the nature of gauge interaction by giving a so-called topological mass to a gauge field without breaking the gauge symmetry. We investigate how a dynamical mass of fermion is affected by the topological mass in the non-perturbative Schwinger-Dyson method.
