The gauge technique in supersymmetric QED2

Abstract

The authors construct an extension of the gauge technique to two-dimensional supersymmetric gauge theories. This involves a derivation of the spectral representation of a scalar superpropagator in two dimensions. They apply the method to the massive supersymmetric Schwinger model. In the case that the gauge multiplet mass equals twice that of the matter multiplet they determine the spectral functions of the matter propagator.
