A study of meson-meson potential in the chiral quark model model

An effective potential in a meson-meson system is discussed based on the SU(3) chiral constituent quark model, and the analytic form of the potential is explicitly given. In addition, the effective potential is employed to study the bound state problem of ωϕwhich is related to the new resonance of f0(1810) observed in BESII very recently.

Strangeness s = -6 dibaryon

The structure of $(ΩΩ)_{0^+}$ dibaryon with strangeness $s=-6$ is studied in the extended chiral SU(3) quark model, in which vector meson exchange dominates the short range interaction. The resonating group method (RGM) is adopted, in which the $ΩΩ$ and $CC$ (hidden color) channels are involved. The color screening effect and the effects of mixing of scalar mesons on $(ΩΩ)_{0^+}$ are also investigated.
