The Structure Of Strangeness-5 Dibayon

Content: By using the resonating group method, we study the structure of (?)*Ω_0,1/2 dibaryonwith strangeness -5 in the extended chiral SU(3) quark model. We find the K^* andφmesonsprovide strong repulsion whileσmeson offers more attraction to (?)*Ω_0,1/2 dibaryon in theextended chiral SU(3) quark model. Our results show that the predicted binding energy of (?)*Ωdibaryon is still lower than the threshold of the (?)Ωπchannel, which is the same as those inthe chiral SU(3) quark model, we think (?)*Ωdibaryon may be a narrow width deeply bounddibaryon.
