Abstract
Characteristic properties of the medium-range central attraction of the nucleon-nucleon and hyperon-nucleon interactions are studied in the (3q)-(3q) resonating-group formulation. The SU6 properties of two-baryon systems are extensively incorporated with the explicit flavor symmetry breaking of the full Fermi-Breit residual interaction. It is found that, for a realistic quark-model description of the hyperon-nucleon interaction compatible with the present low-energy experimental data, it is necessary to introduce phenomenological medium-range attraction which is much less than that for the nucleon-nucleon system. Effective meson-exchange potentials from the scalar-meson nonet exchange in the Nijmegen model-F are conveniently employed to generate the needed flavor-dependent central attraction with few parameters determined for each flavor exchange symmetry.Keywords
