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.
