| 英文摘要 | We expand Salamanca SU(2) chiral quark model to SU(3) one and calculate promising dibaryon candidates with strangeness S = -3, -6 in the framework of resonating group method. We find that, besides OmegaOmega, the mass of NOmega state is about 23-38 MeV lower than its threshold, it might appear as a bound state or a narrow resonance. The effect of K and eta exchanges on the masses of strangeness and nonstrangeness systems has been studied and found to be negligible for nonstrangeness systems. However this effect brings some changes (about tens of MeV) on the masses of strangeness systems. We have also studied the sensitivities of binding energy and root mean square radius to the mass of s-quark. |
