论文摘要
我们通过采用相关夸克模型中的介子波函数来评估$ k_0^*（1950）$和$ k_0^*（2130）$的强效率。通过与实验测量值进行比较，可以将$ k_0^*（2130）$分配为$ k_0^*（3^3p_0）$，而$ k_0^*（1950）$似乎是一种异国情调的状态，因为它的宽度无法在$^3p_0 $型号内合理地复制。我们还预测，$ k_0^*（2^3p_0）$ state的质量约为1811美元，宽度约为656美元，而$ k_0^*（4^3p_0）$ state的质量约为$ 2404 $ MEV，宽度约为180美元。
We have evaluated the strong decays of the $K_0^*(1950)$ and $K_0^*(2130)$ within the $^3P_0$ model, by employing the meson wave functions from the relativized quark model. By comparing with the experimental measurements, the $K_0^*(2130)$ could be assigned as $K_0^*(3^3P_0)$, while the $K_0^*(1950)$ seems like an exotic state, because its width can not be reasonably reproduced within the $^3P_0$ model. We also predict that the $K_0^*(2^3P_0)$ state has a mass of about $1811$ MeV and a width of about $656$ MeV, while the $K_0^*(4^3P_0)$ state has a mass of about $2404$ MeV and a width of about $180$ MeV.
