Description

We construct a non-trivial and renormalized extension of the Nambu and Jona-Lasinio (NJL) model. This model is analogous in form to the linear σ-model. However, given the Nc dependence of the coupling constant, diagrams involving mesonic internal lines are absent in leading order, as opposed to the linear σ-model. Meson properties are systematically improved in the present calculations as compared to usual Pauli-Villars regularized versions
