Meson exchange and quark pairing

A quark pairing mechanism is reviewed that generates the strong interactions of meson exchange character. It originates from quark (or antiquark) reflections in the color confining hadronic surface region and proceeds by quark exchange scattering in conjunction with quark-antiquark condensate propagation across the QCD vacuum. This mechanism links chiral invariance with color confinement and represents a common basis for various low energy models including vector meson dominance, Goldberger-Treiman relations, πN S-wave scattering, and the broken SU(3) symmetry. It also appears to reconcile nuclear models with the finite size of the nucleon
