Strangeness s = -6 dibaryon

Abstract

The structure of $(\Omega \Omega {)}_{0^{+}}$ 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 $\Omega \Omega$ and $CC$ (hidden color) channels are involved. The color screening effect and the effects of mixing of scalar mesons on $(\Omega \Omega {)}_{0^{+}}$ are also investigated.
