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

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](0,0

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