✦ Synopsis

Scattering observables of the NN and YN interactions and nuclear-matter properties are investigated in a recent quark model developed for a unified description of the NN and YN systems. The model is formulated in the (3q)-( 39 ) resonating-group method, and incorporates the full Fermi-Breit interaction with explicit quark-mass dependence and the minimum meson-exchange potentials of scalar and pseudo-scalar meson nonets directly coupled to quarks. Reasonable agreement with the available experimental data is obtained for the NN properties and the low-energy YN cross sections.

Predictions for the C+p and Ap scattering observables at intermediate energies are very much modeldependent, suggesting the importance of further experimental studies of these quantities.
