论文摘要
$ M = 1868 \ pm 8^{+ 40} _ { - 57} $ meV和$ m = 2073 \ pm 94^{+ 245} _ { - 240} $ meV是相同的状态($ k_2^*(1980)$)的两个观察到的结构。 $ k_2^*(1980)$的低质量状态为$ 2^3p_2 $,高质量状态为$ k_2^*(1980)$ as $ 1^3f_2 $在这封信中。该分析为我们带来了非常重要的标准,用于分配观察到的$ k_2^*(1980)$,并提出了该分配的实验结果。此外,对$ k_2^*$ family的高激发进行了一些部分衰减宽度的预测。这项研究对于建立和寻找未来更高的激发至关重要。
Two observed structures with $M=1868 \pm 8^{+ 40}_{- 57}$ MeV and $M=2073 \pm 94^{+ 245}_{- 240}$ MeV are the same states ($K_2^*(1980)$) in PDG.The analysis of the mass spectrum and the calculation of the strong decay of $K_2^*$ mesons support the low mass state of $K_2^*(1980)$ as $2^3P_2$ and the high mass state of $K_2^*(1980)$ as $1^3F_2$ in this letter. This analysis brings us very important criterion for the assignment of the observed $K_2^* (1980)$ and experimental findings for this assignment is suggested. Additionally, prediction of some partial decay widths are made on the high excitations of $K_2^*$ family. This study is crucial to establishing and searching for their higher excitations in the future.
