摘要

用相对论夸克模型计算了重夸克的质谱。假设具有相同性质的夸克和反夸克之间的有效相互作用是包含湮灭项的单胶子交换和具有相对论修正的标量和矢量线性限制势的混合的总和。详细讨论了湮灭和相对论修正项对夸克态超细分裂的影响，并在质谱上得到了与观测到的实验数据很好的拟合。

Heavy quarkonium mass spectra in a relativistic quark model

The mass spectra of heavy quarkonia are calculated with the relativistic quark model.The effective interaction between a quark and an antiquark of the same flavor is assumed to be the sum of the one_gluon exchange with the inclusion of annihilation terms and the mixture of scalar and vector linear confining potentials with the relativisic corrections.The effects of the annihilation and the relativistic correction terms on the hyperfine splittings of quarkonium states are discussed in detail,and a good fit to the observed experimental data is obtained on the mass spectra.
