Simulating the massive Schwinger model with chiral defect fermions

By A. Jaster and Hamburg (Germany) Deutsches Elektronen-Synchrotron (DESY)

Abstract

Some time ago Kaplan proposed a new model for the description of chiral fermions on the lattice by adding an extra dimension for the fermions. A variant of this proposal was introduced by Shamir and can be used to describe vector-like theories in even dimensions. We used this model for the simulation of the massive Schwinger model at different gauge couplings. The prediction that the fermion mass gets only multiplicative renormalization was tested and verified.
