We analyze the charmonium states by testing a phenomenological nonrelativistic potential and propose a new set of parameters. This new set of parameters is fixed using only the lowest lying S-wave states of charmonia where the spin-orbit and the 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 the tensor interactions. Calculations showed that the nonrelativistic potential model with a phenomenologically defined parameters was indeed a good approximation for describing the charmonium states.

非相对论 $$c\bar{c}$$ cc ¯ 势的检验

我们通过测试现象学的非相对论潜力来分析魅力状态，并提出了一组新的参数。这组新参数仅使用自旋轨道和张量相互作用不会贡献的 Charmonia 的最低 S 波状态来固定。拟合参数后，我们考虑自旋轨道和张量相互作用，分析了魅力状态的整个精细结构。计算表明，具有现象学定义参数的非相对论势模型确实是描述魅力状态的良好近似。
