In this article we give a detailed discussion of the mass perturbation theory of the massive Schwinger model. After discussing some general features and briefly reviewing the exact solution of the massless case, we compute the vacuum energy density of the massive model and some related quantities. W

The Schwinger model is quantum electrodynamics with massless fermions in two dimensions. It is known that the asymptotic states of the theory contain no states corresponding to free fermions ("quark trapping") and that local charge conservation is spontaneously broken ("Higgs phenomenon"). We invest
The ordinary Schwinger model is studied for a one-parameter class of regularizations commonly used in the study of the anomalous chiral Schwinger model and shown to be sensible and in fact solvable for a range of values of the parameter. There is a massless fermion in the spectrum except at the valu
