Vacuum Functional and Fermion Condensate in the Massive Schwinger Model
arXiv:hep-ph/9507279 · doi:10.1016/0370-2693(95)01181-O
Abstract
We derive a systematic procedure of computing the vacuum functional and fermion condensate of the massive Schwinger model via a perturbative expansion in the fermion mass. We compute numerical results for the first nontrivial order.
