Dynamical breaking of gauge symmetry in Abelian gauge theories in two dimensions

Abstract:

Two-dimensional Abelian gauge theories with nonstandard fermion content are analyzed. One model contains N fermions with different electric charges and the other has a left-right-asymmetric fermion content. The operator solutions are explicitly constructed in a covariant gauge and a noncovariant gauge. In both models the gauge and the chiral symmetries are broken spontaneously. The direction of this breakdown is dictated by the axial anomaly. The spectrum of the minimal theory consists of one massive boson and one massless boson for both types of theories. It is argued that the left-right-asymmetric model is inappropriate to test the most-attractive-channel hypothesis. © 1983 The American Physical Society.
