✦ Synopsis


A quark-meson coupling model based on SU(3) L Γ— SU(3) R symmetry and scale invariance is proposed. We apply this chiral SU(3) quark mean-field model to investigate strange hadronic matter including Ξ›, Ξ£ and Ξ hyperons. With the symmetry-breaking term, all the hyperon potentials are reasonable. The effective baryon masses, binding energy and hyperon ratios are discussed with four types of confining potentials.

Quark-chiral field interaction is studied in terms of the linear realization of the Lagrangian which is invariant under the SU(3)L Γ— SU(3)R infinitesimal transformation and then is applied to the hyperon-nucleon scattering calculation in the framework of RGM. It is shown that the SU(3) chiral scalar

The energies of the (0S) 6 six quark cluster states are calculated in the chiral SU(3) quark model. The results show that some states with high strangeness have more attraction from the chiral SU(3) coupling, and this feature is interesting in discussing if there exists some new narrow width six qua

We investigate the effects on mean-field quantities and nuclear pairing in symmetric nuclear matter of the density-dependent effective nucleon-scalar-meson coupling that is obtained in a Οƒ -Ο‰ quarkmeson coupling model. We find that the effective coupling strongly modifies mean-field quantities, such
