We examine QED 1+1 (the massive Schwinger model) to extend existing perturbation results in m f /m b , and compare our results with lattice and DLCQ calculations.

The Gauge Technique has been applied to QED2+1 in the quenched case with infrared subtraction. The behaviour of the fermion propagator near the threshold is then found to be S(p) → (γ · p+m) (p −m) ( p −m 2m ) exp(− ης 2 ), where ς = e/(4πm) and this is gauge invariant except the exponential factor. We also find a spectral function in the Landau and Yennie like gauge. The propagators S(p) are e...
