摘要:

夸克偶素系统的质谱可以用不同的唯象势描述。在本工作中,类重夸克偶素($c\bar{c}$和$b\bar{b}$)的{ \color{black}共振}态被认为是转振态.本文研究了一个由非相对论薛定谔方程的经验解导出的参数化振转模型,模型的修正由色超精细相互作用和介子的自旋轨道相互作用组成.我们{ \color{black}}得到了粲鎓和底鎓的高激发态质谱,并将结果与现有的实验数据进行了比较,结果符合得很好。

英文摘要:

Mass spectra of quarkonium systems can be described by different phenomenological potentials. In the present work, the {\color{black}resonance} states of heavy quarkonium like ($c\bar{c}$ and $b\bar{b}$) are considered as the rovibrational states. We study a parameterized rovibrational model derived from the empirical solution of the nonrelativistic Schrödinger equation with Morse potential, the corrections are composed of colour hyperfine interaction and spin-orbit interaction of mesons. We {\color{black}obtain} the high excited state mass spectra of charmonium and bottomonium comparing the results in reasonable agreement with the present experimental data.
