Nonperturbative Aspects of the two-dimensional Massive Gauged Thirring Model
arXiv:1408.2917 · doi:10.1142/S0217751X1450122X
Abstract
In this paper we present a study based on the use of functional techniques on the issue of insertions of massive fermionic fields in the two-dimensional massless Gauged Thirring Model. As it will be shown, the fermionic mass contributes to the Green's functions in a surprisingly simple way, leaving therefore the original nonperturbative nature of the massless results still intact in the massive theory. Also, by means of complementarity, we present a second discussion of the massive model, now at its bosonic representation.
