binding energy of the six-quark system with strangeness s = -3 is investigated under the chiral SU(3) constituent quark model in the framework of RGM. The calculations of the single N Omega channel with spin S = 2 and the single Delta Omega channel with spin S = 3 are performed. The results show that both systems could be dibaryons and the interaction induced by the chiral field plays a very important role on forming bound states in the systems considered. The phase shifts and scattering lengths in corresponding channels are also given.
