Abstract

The dynamic mechanism of short range interactions between u/d quarks remains an open and challenging problem. In order to reveal this quark dynamics, we perform a systematic analysis of NN, D₀₃, and D₃₀ systems in the (extended) chiral SU(3) constituent quark models. By comparing results calculated with different models and different parameter sets, the effects of one gluon exchange and vector meson exchange terms are carefully examined. The results indicate that the vector meson exchange interactions dominate the short range interactions between u/d quarks, whereas the small residual one gluon exchange coupling strength is also allowed.

揭示NN、D03和D30系统中u/d夸克之间的短程相互作用

u/d夸克间短程相互作用的动力学机制仍然是一个开放和具有挑战性的问题。为了揭示这种夸克动力学，我们在（扩展的）手性SU(3)组成夸克模型中对NN， D03和D30系统进行了系统分析。通过比较不同模型和不同参数集的计算结果，仔细考察了单胶子交换项和矢量介子交换项的影响。结果表明，在u/d夸克之间的短程相互作用中，矢量介子交换相互作用占主导地位，但也允许存在较小的剩余1胶子交换耦合强度。
