Book 1995essfully meson properties. It possesses solitonic solutions which are identified as baryons. Via functional integral techniques a Faddeev equation for baryons describing them as bound states of a diquark and a quark is derived. Finally, a unification of these two complementary pictures of baryons is proposed.

The Effective Meson Theory,e generic form predates QCD. It was as early as 1961 that Y. Nambu and G. Jona-Lasinio studied a model with a chirally symmetric local four-point interaction [NJL61]. They interpreted the underlying fermion fields as nucleons. They found dynamical breaking of chiral symmetry and pseudoscalar Goldsto
