Ad. Dutra, MAPPING CORRELATION-FUNCTIONS OF SCHWINGER AND AXIAL MODELS, Journal of physics. G, Nuclear and particle physics, 19(8), 1993, pp. 1127-1136
We show that all Green's functions of the Schwinger and axial models c
an be obtained one from the other. In particular, we show that the two
models have the same chiral anomaly. Finally it is demonstrated that
the Schwinger model can keep gauge invariance for an arbitrary mass, d
ispensing with an additional gauge group integration.
