✦ Synopsis

The previous analysis of the short-range NN repulsion originating from the Goldstone boson exchange hyperfine interaction between constituent quarks is revisited. We study in which respects the repulsion depends on the radial form of the spin-spin quark-quark force. We show that while the radial form affects the structure of the 6Q wave function, the short-range repulsion in the NN system persists in any case. We extend our analysis to other YN and YY (flavor octet-octet) systems and demonstrate that the flavor-spin hyperfine interaction implies a short-range repulsion in these B = 2 systems as well.

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 interact
