Chiral Dynamics and Fermion Mass Generation in Three Dimensional Gauge Theory
M. C. Diamantini G. W. Semenoff P. Sodano
Abstract
We examine the possibility of fermion mass generation in 2+1- dimensional gauge theory from the current algebra point of view.In our approach the critical behavior is governed by the fluctuations of pions which are the Goldstone bosons for chiral symmetry breaking. Our analysis supports the existence of an upper critical number of Fermion flavors and exhibits the explicit form of the gap equation as well as the form of the critical exponent for the inverse correlation lenght of the order parameter
