Abstract:

An effective model for low energy hadronic interactions is formulated arising form the bosonization of a Nambu-Jona Lasinio type Lagrangian including all chiral invariant multiquark effective interactions. The bosonized Lagrangian includes non-renormalizable quark-meson vertices which are next-to-leading in the low energy inverse cutoff expansion. Their relevance is explicitely discussed for the two point vector currents Green's function.
