Cp. Natividade et Ad. Dutra, BRST-BFV FORMALISM FOR THE GENERALIZED SCHWINGER MODEL, Zeitschrift fur Physik. C, Particles and fields, 75(3), 1997, pp. 575-578
We derive the Wess-Zumino scalar term of the generalized Schwinger mod
el both in the singular and nonsingular cases by using BRST-BFV framew
ork. The photon propagators are also computed in the extended Lorentz
gauge.
