Abstract. We review the application of non-relativistic constituent quark models to study one, two and three non-strange baryon systems. We present results for the baryon spectra, potentials and observables of the NN, N∆, ∆∆ and NN * (1440) systems, and also for the binding energies of three non-strange baryon systems. We make emphasis on observable effects related to quark antisymmetry and its interplay with quark dynamics.

The binding energy of nuclear matter including exchange and pionic effects is calculated in a quark-meson coupling model with massive constituent quarks. As in the case with elementary nucleons in QHD, exchange effects are repulsive. However, the coupling of the mesons directly to the quarks in the nucleons introduces a new effect on the exchange energies that provides an extra repulsive contribution to the binding energy. Pionic effects are not small. Implications of such effects on observables are discussed.

“…The π-quark coupling constant is determined [19] by comparing the asymptotic behavior of the nucleon-nucleon one-pion-exchange potentials at the quark level and for point nucleons: (2), and includes the exchange effects of the σ and ω. The new readjustment of g σ and g ω to saturate nuclear matter at the right place is relatively small, as seen in Table I, entry (5).…”
