  The Nambu-Jona-Lasinio model of the deuteron suggested by Nambu and
Jona-Lasinio (Phys. Rev. 124 (1961) 246) is formulated from the first
principles of QCD. The deuteron appears as a neutron-proton collective
excitation, i.e. a Cooper np-pair, induced by a phenomenological local
four-nucleon interaction 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 nuclear states and accounting for contributions of nucleon-loop anomalies
which are completely determined by one-nucleon loop diagrams. The dominance of
contributions of nucleon-loop anomalies to effective Lagrangians of low-energy
nuclear interactions is justified in the large N_C expansion, where N_C is the
number of quark colours.
