Abstract

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.
