Xi Omega and Xi*Omega dibaryons in SU(3) chiral quark model

The binding energy of the six quark system with strangeness s = -5 is inves tigated by the SU(3) chiral constituent quark model. The single Xi*Omega ch annel calculation with spin S = 0 and the coupled Xi Omega - Xi*Omega chann el calculation with spin S = 1 are considered. It is shown that in the spin S = 0 case, the binding energy of Xi*Omega is ranged from 80.0 to 92.4 MeV , while in the S = I case, the additional Xi*Omega channel increases the bi nding energy of Xi Omega to a range of 26.2 - 32.9 MeV.
