Abstract:

Scattering observables of the NN and YN interactions are investigated in a recent quark model developed for the simultaneous description of the NN and YN systems. The model is formulated in the (3q)-(3q) resonating-group method and incorporates a phenomenological quark-confining potential, the full Fermi-Breit interaction with explicit quark-mass dependence, and minimum effective meson-exchange potentials of scalar and pseudo-scalar meson nonets directly coupled to quarks. The differential cross sections and some spin observables of the np and pp scattering are reasonably reproduced. Predictions for the Σ+ p and Λp scattering observables at intermediate energies are very much model-dependent, suggesting the importance of further experimental studies on these quantities.
