摘要:

在具有两种空间波函数的$^3P_0$模型中计算了$5^1S_0$ $q\bar{q}$态的强衰变.通过对$π(2360)$、$η(2320)$、$X(2370)$和$X(2500)$的模型预测与实验数据的比较,我们认为$π(2360)$、$η(2320)$和$X(2500)$可以被指定为$5^1S_0$介子九重态的成员,而对$X(2370)$的$5^1S_0$指定并不受其宽度的影响.预计$5^1S_0$ K介子的质量约为2418 MeV,宽度约为163 MeV或225 MeV。

英文摘要:

The strong decays of the $5^1S_0$ $q\bar{q}$ states are evaluated in the $^3P_0$ model with two types of space wave functions. Comparing the model expectations with the experimental data for the $π(2360)$, $η(2320)$, $X(2370)$, and $X(2500)$, we suggest that the $π(2360)$, $η(2320)$, and $X(2500)$ can be assigned as the members of the $5^1S_0$ meson nonet, while the $5^1S_0$ assignment for the $X(2370)$ is not favored by its width. The $5^1S_0$ kaon is predicted to have a mass of about 2418 MeV and a width of about 163 MeV or 225 MeV.
