摘要
给出了Cornell势到v2/c2级次的所有相对论修正和湮没修正.计算了重夸克偶素的质量谱,并与实验数据符合较好.系统地讨论了湮没项和v2/c2级次的相对论修正项对能谱分裂的作用.
The annihilation and relativistic corrections to the Cornell potential is given and the mass spectra of heavy quarkonia are calculated. A good fit to available experimental data on the mass spectra is obtained and the effects of both the annihilation and the relativistic corrections on the hypersplittings of quarkonium states are discussed.
