Configuration mixing and effective baryon-baryon interactions

The effective baryon-baryon interaction is studied in the refined quark delocalization color screening model (QDCSM), in which the different quark clusterings are fully taken into account, instead of controlling by a variational delocalization parameter epsilon(s) between two three-quark clusters. The symmetry bases are employed to do the calculation, all possible configurations for two-quark clusters are considered. The results obtained are very similar to those of QDCSM. It is inferred that the delocalization parameter epsilon(s) used in QDCSM is an economic and effective way to describe the mixing of quarks between baryons. The relativized quark model is also employed to study the relativistic effect on the effective potentials between two baryons.
