摘要
从ＳＵ（３）Ｌ×ＳＵ（３）Ｒ无穷小变换下不变拉氏量的线性表示形式出发，给出了夸克－夸克间的相互作用势．分析表明ＳＵ（３）标量手征场对解释ＡＮ相互作用中自旋关系的性质是很重要的．
A quark-quark potential is derived from the linear expression of the Lagrangian Which is invariant under the SU(3)L×SU(3)R infinitesimal transformation,and further used to make a qualitative analysis on the Λ-N interaction.The result shows that the SU(3)chiral scalar fields are important in explaining the spin-dependence feature of theΛ-N interaction.
