Configuration mixing and effective baryon-baryon interactions

Abstract

The effective baryon-baryon interactions 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 3-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 that 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.
