The Nambu-Jona-Lasinio model of light nuclei

The Nambu-Jona-Lasinio model of the deuteron suggested by Nambu and Jona-La sinio (Phys. Rev. 124 (1961) 246) is formulated from the first principles o f QCD. The deuteron appears as a neutron-proton collective excitation, i.e. a Cooper np-pair, induced by a phenomenological local four-nucleon interac tion in the nuclear phase of QCD. The model describes the deuteron coupled to itself, nucleons and other particles through one-nucleon loop exchanges providing a minimal transfer of nucleon flavours from initial to final nucl ear states and accounting for contributions of nucleon-loop anomalies which are completely determined by one-nucleon loop diagrams. The dominance of c ontributions of nucleon-loop anomalies to effective Lagrangians of low-ener gy nuclear interactions is justified in the large N-C expansion, where N-C is the number of quark colours.
