The Schwinger Mass in the Massive Schwinger Model
arXiv:hep-ph/9507331 · doi:10.1016/0370-2693(96)00695-8
Abstract
We derive a systematic procedure to compute Green functions for the massive Schwinger model via a perturbation expansion in the fermion mass. The known exact solution of the massless Schwinger model is used as a starting point. We compute the corrections to the Schwinger mass up to second order.
