重夸克偶素的超精细劈裂和轻子衰变率研究

Study on the Hyperfine Splitting and Leptonic Decay Rates of Heavy Quarkonia

考虑相对论修正的夸克-反夸克势和相对论修正的矢量衰变常数,在相对论夸克模型下计算了重夸克偶素的质量谱和轻子衰变率,所得到的质量谱和轻子衰变率与实验上肯定的数据符合.

A calculation for mass spectra and leptonic decay rates of heavy quakonia is given in a relativistic quark model, which includes full relativistic corrections to the quark-antiquark potential and the vector decay constants. Both the obtained mass spectra and leptonic decay rates agree well with the available experimental data.
