On the Phase Structure of the Schwinger Model with Wilson Fermions

Abstract

We study the phase structure of the massive one flavour lattice Schwinger model on the basis of the finite size scaling behaviour of the partition function zeroes. At $\beta =0$ we observe and discuss a possible discrepancy with results obtained by a different method.
