Bosonization and the lattice Gross-Neveu model

Abstract

We consider a lattice version of the bosonized Gross-Neveu model. It is explicitely chiral symmetric and its numerical simulation does not involve any anticommuting field. We study its non trivial $1/N$ expansion up to the next-to-leading term comparing the results with explicit numerical simulations.
