Abstract：
We investigate the binding energy of six-quark systems with strangeness s=－3 under the constituent quark model in the framework of RGM. The single NΩ channel with spin S=2 and the single ΔΩ channel with spin S=3 are considered, respectively. The results show that both two systems can form loosely bound states: the binding energies are ranged from 3.5—12.7 MeV for NΩ and 4.4—14.2 MeV for ΔΩ system, respectively.
