โœฆ Synopsis

In the framework of the SU(3) chiral quark model, the S-wave baryon-baryon bound states are investigated. It is found that according to the symmetry character of the system and the contributions from chiral fields, there are three types of bound states. The states of the first type, such as aa and ~*a are deeply bound dibaryon with narrow widths. The second type states, N*A , AA are also bound states, but with broad widths. ~F/-E*fl, EF-, and Nf~ are third type states. They, like d, are weakly bound only if the chiral fields can provide attraction between baryons.

The possible candidates of S-wave dibaryons with various strange numbers are studied under the chiral SU(3) quark model. It is shown that there are three types of baryon-baryon bound states. The states of the first type are called deuteron-like states. If chiral fields can provide enough attraction

The chiral SU(3) quark model is extended to include coupling between vector chiral field and quarks. By using this model, the phase shifts of NN scattering for different partial waves are studied. The results are very similar to those of the chiral SU(3) quark model calculation, in which one gluon e

Quark-chiral field interaction is studied in terms of the linear realization of the Lagrangian which is invariant under the SU(3)L ร— 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

A quark-meson coupling model based on SU(3) L ร— 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 ฮ›, ฮฃ and ฮž hyperons. With the symmetry-breaking term, all the hyperon potentials are reasonable.
