摘　　要：The binding energy of the six quark system with strangeness s=-5 is investigated by the SU(3)chiral constituent quark model.The single ■^(*)Ω channel calculation with spin S=Q and the coupled ■Ω-■^(*)Ω channel calculation with spin S=1 are considered.It is shown that in the spin S=0 case,the binding energy of ■^(*)Ω is ranged from 80.0 to 92.4MeV,while in the S=1 case,the additional ■^(*)Ω channel increases the binding energy of ■Ω to a range of 26.2-32.9 MgV.
