Meson Properties in a renormalizable version of the NJL model

High Energy Physics - Phenomenology 2009-10-31 v1

Abstract

In the present paper we implement a non-trivial and renormalizable extension of the NJL model. We discuss the advantages and shortcomings of this extended model compared to a usual effective Pauli-Villars regularized version. We show that both versions become equivalent in the case of a large cutoff. Various relevant mesonic observables are calculated and compared.
