Equivalence of the massive Thirring model with a U(1) gauge theory

Journal Article · · Phys. Rev. D; (United States)
We prove the equivalence (both classical and quantum) of the massive Thirring model with U(1) gauge theory containing the Thirring fermion, the sine-Gordon scalar, and a vector field as fundamental degrees of freedom. The construction is generalized to the SU(/ital N/) Abelian extension of the Thirring model. The mass of the scalar field is calculated in the leading order in the 1//ital N/ expansion and to first order in perturbation theory. The result agrees with the known exact result.
