N Omega and Delta Omega dibaryons in a SU(3) chiral quark model

binding energy of the six-quark system with strangeness s = -3 is investiga ted 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 sin gle Delta Omega channel with spin S = 3 are performed. The results show tha t 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 c onsidered. The phase shifts and scattering lengths in corresponding channel s are also given.
