| 英文摘要 | Within the framework of the resonating group method, the binding energy of one-channel Delta Delta((3.0))(d*) and Delta Delta((0.3)) are studied in the chiral SU (3) quark cluster model. it is shown that the binding energies of the systems are a few tens of MeV. The behaviour of the chiral field is also investigated by comparing the results with those in the SU (2) and the extended SU (2) chiral quark models. It is found that the symmetry property of the Delta Delta system makes the contribution of the relative kinetic energy operator between two clusters attractive. This is very beneficial for Forming the bound dibaryon. Meanwhile the chiral-quark field coupling also plays a very important role in binding. The S-wave phase shifts and the corresponding scattering lengths of the systems are also given. |
