  The relativistic field theory model of the deuteron (RFMD) is reformulated
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 RFMD describes
the deuteron coupled to hadrons 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 expansion, where N is the number of
quark colours.
