摘要
利用能量依赖的夸克-反夸克间自旋-自旋作用势建立了介子超精细质量劈裂公式。数据分析表明该公式能统一描述基态和激发态、同位旋为零及非零介子的超精细质量劈裂。
A new formula for the hyperfine mass pplitting of mesons is established by using energy- dependent spin--spin potential between quark and antiquark. Data analysis indicates that this for- mula is capable of describing hyperfine mass splitting of mesons in ground--state or excited--state with isospin zero or nonzero.
