Contribution

It introduces a refined approach to baryon interactions by fully considering quark cluster configurations, validating the effectiveness of the delocalization parameter in the model.

Findings

Results align with previous QDCSM findings.

Full configuration consideration confirms the delocalization parameter's effectiveness.

Supports the use of symmetry bases in baryon interaction calculations.

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.
