Quark delocalization, color screening, and dibaryons.
The quark delocalization and color screening model, a quark potential model, is used for a systematic search of dibaryon candidates in the u, d and s three flavor world. Color screening which appears in unquenched lattice gauge calculations and quark delocalization (which is similar to electron delocalization in molecular physics) are both included. Flavor symmetry breaking and channel coupling...
متن کاملdibaryon in the extended quark - delocalization , color - screening model
The quark-delocalization, color-screening model (QDCSM), extended by inclusion of a one-pion-exchange (OPE) tail, is applied to the study of the deuteron and the d dibaryon. The results show that the properties of the deuteron (an extended object) are well reproduced, greatly improving the agreement with experimental data as compared to our previous study (without OPE). At the same time, the ma...
متن کاملQuark delocalization, color screening, and nuclear intermediate range attraction.
We consider the effect of including quark delocalization and color screening, in the nonrelativistic quark cluster model, on baryon-baryon potentials and phase shifts. We find that the inclusion of these additional effects allows a good qualitative description of both.
متن کاملDibaryons in the Quark Cluster Model
In the framework of RGM , the binding energy of one channel ∆∆ (3,0) (d *) and ∆∆ (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 behavior 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 ...
متن کاملNω and ∆ω Dibaryons in Su(3) Chiral Quark Model
The binding energy of the six quark system with strangeness s=-3 is investigated under the chiral SU(3) constituent quark model in the framework of RGM . The calculations of the single NΩ channel with spin S=2 and the single ∆Ω channel with spin S=3 are performed. The results show that both systems could be dibaryons and the interaction induced by the chiral field plays a very important role on...
