摘要
用推广的矩分析方法对过程e+e-→J/ψ→V+X(JPC),X(JPC)→3P进行了研究,着重讨论了多态耦合的共振峰复杂结构,并由此得到了一些矩的关系式.利用这些关系式,可以通过对实验数据的分析来确定宽共振峰的耦合模式,进而确定它们的质量,宽度,自旋等重要性质。
The process e+e-→ J/ψ→ V + X(JPC), X(JPC) → 3P is studied using the generalized moment analysis method. The complicated structure of the resonance peak is discussed by use of multi-states coupling modes and some relations of moments are obtained. The coupling mode of the wide resonance peak can be determined by analysing the experimental data. The masses, widths and spins and so on of these states can also be determined.
