  The 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.
