英文摘要 | In the framework of the SU(3) chiral quark model, the S-wave baryon-baryon bound states are investigated. It is found that according to the symmetry character of the system and the contributions from chiral fields, there are three types of bound states. The states of the first type, such as [Omega Omega]((0,0)) and [Xi*Omega]((0,1/2)) are deeply bound dibaryon with narrow widths. The second type states, [Sigma*Delta]((0,5/2)), [Delta Delta]((3,0)) are also bound states, but with broad widths. [Xi Omega - Xi*Omega]((1,1/2)), [Xi Xi]((0,1)), and [Xi Omega]((2,1/2)) are third type states. They, like d, are weakly bound only if the chiral fields can provide attraction between baryons. |
