激发光$^3S_1$矢量介子的可能归属

Possible Assignment of Excited Light $^3S_1$ Vector Mesons

摘要:

本文重新分析了用$q\bar{q}$夸克模型还不能很好地建立的3 $^3S_1$和4 $^3S_1$轻介子分配问题。分别用Regge轨线和$^3P_0$衰变模型研究了观测态的质量和宽度,并对丢失态进行了预测。通过计算结果与最新实验结果的比较,我们认为$ρ(2150)$的不一致数据可能包括两个相似的结构$ρ(4^3S_1)$和$ω(4^3S_1)$。此外,问题的$K^*(2^3S_1)$分配,两个观察状态$K^*(1410)$和$K^*(1680)$,进行了研究,有几种可能的解释。

英文摘要:

We reanalyze the problems in the assignment of 3$^3S_1$ and 4$^3S_1$ light mesons, which have not yet been well established with the $q\bar{q}$ quark model. Regge trajectories and the $^3P_0$ decay model are used respectively to study the mass and width of the observed states and predict the missing ones. By comparing our calculations with the latest experiments, we suggest that the inconsistent data of $ρ(2150)$ may include two similar structures $ρ(4^3S_1)$ and $ω(4^3S_1)$. In addition, the problem of the $K^*(2^3S_1)$ assignment, with two observed states $K^*(1410)$ and $K^*(1680)$, is investigated, with several possible explanations.
