非相对论性$c\bar{c}$势的检验

Test of the nonrelativistic $c\bar{c}$ potential

Ulugbek Yakhshiev

摘要:

我们通过测试唯象非相对论势来分析粲偶素态,并提出了一组新的参数。这组新的参数是固定的,只使用最低的躺在S波状态的charmonia的自旋轨道和张量相互作用将不会作出贡献。在对参数进行拟合后,考虑自旋轨道相互作用和张量相互作用,分析了粲偶素态的整体精细结构。计算表明,用唯象定义的参数建立的非相对论势模型确实是描述粲偶素态的良好近似。

英文摘要:

We analyze the charmonium states by testing a phenomenological nonrelativistic potential and propose a new set of parameters. This new set of parameters are fixed using only the lowest lying S-wave states of charmonia where the spin-orbit and tensor interactions will not contribute. After fitting the parameters we analyze the whole fine structure of charmonium states taking into account the spin-orbit and tensor interactions too. Calculations showed that the nonrelativistic potential model with the phenomenologically defined parameters is indeed well approximation for describing the charmonium states.
