The lattice Schwinger model with SLAC fermions is analyzed with two methods: a Hartree-Fock calculation of the ground state wave function, and a weak coupling approximation involving a truncated SLAC derivative. It is shown that a Goldstone boson of chiral symmetry is actually present, but in the weak coupling limit it acquires infinite velocity. © 1985.

Abstract
The lattice Schwinger model with SLAC fermions is analyzed with two methods: a Hartree-Fock calculation of the ground state wave function, and a weak coupling approximation involving a truncated SLAC derivative. It is shown that a Goldstone boson of chiral symmetry is actually present, but in the weak coupling limit it acquires infinite velocity. © 1985.
