Analysis of the Lee-Yang zeros in a dynamical mass generation model in three dimensions

Abstract We investigate a strongly U(1) gauge theory with fermions and scalars on a three dimensional lattice and analyze whether the continuum limit might be a renormalizable theory with dynamical mass generation. Most attention is paid to the weak coupling region where a possible new dynamical mass generation mechanism might exist. There we investigate the mass of the composite fermion, the chiral condensate and the scaling of the Lee-Yang zeros.
