Scattering observables of the NN and YN interactions in the SU6 quark model

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 meth od and incorporates a phenomenological quark-confining potential, the full Fermi-Breit interaction with explicit quark-mass dependence, and minimum ef fective meson-exchange potentials of scalar and pseudo-scalar meson nonets directly coupled to quarks. The differential cross sections and some spin o bservables of the np and pp scattering are reasonably reproduced. Predictio ns for the Sigma(+)p and Lambda p scattering observables at intermediate en ergies are very much model-dependent, suggesting the importance of further experimental studies on these quantities.
