【Abstract】 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.更多还原
