摘要
在推广的手征SU(3)夸克模型下讨论了核子 -核子散射过程和矢量介子交换势 .给出了赝标π介子和矢量 ρ和ω介子的GCM中心力的交换势和NN散射 14个分波的相移 .研究表明 ,矢量介子交换势可以替代单胶子交换势以解释核力的短程排斥 .
In this work, the vector meson exchange effect in NN interaction is studied on quark level in the extended chiral SU(3) quark model. The π,ρ and ω-meson exchange GCM potentials of central force and NN scattering phase shifts for all scattering partial waves are given. It shows that the vetor meson exchange potential can substitute one-gluon exchange (OGE) potential to explain repulsive core of the NN interaction.
