New finite-lattice study of the massive Schwinger model - art. no. 034508

A new finite lattice calculation of the low lying bound state energies in t he massive Schwinger model is presented, using a Hamiltonian lattice formul ation. The results are compared with recent analytic series calculations in the low mass limit, and with a new higher order non-relativistic series wh ich we calculate for the high mass limit. The results are generally in good agreement with these series predictions, and also with recent calculations by light cone and related techniques.
