论文摘要
在这项工作中，我们研究了涉及Kaonic共振$ k（1460）$，$ k_1（1270）$和$ k_1（1400）$的最终州的$ ϕ（2170）$的强效率，最近已由Besiii Collaporation提取了实验数据。此处开发的形式主义是基于解释$ ϕ（2170）$和$ k（1460）$作为由三龙动力学产生的状态，这是受我们较早作品的启发。对于$ k_1（1270）$和$ k_1（1400）$，我们研究了不同的描述，例如属于非轴向共振的状态的混合物，或者是源自vector-pector-pector-pector-pector-pector-pector-pector-pector-pector-pector-pector-secudoscalar dynamics的状态。 $ k^+（1460）k^ - $，$ k^+_ 1（1400）k^ - $和$ k^+_ 1（1270）k^ - $获得的部分宽度之间的比率与实验结果兼容，从而增强了$ ϕ（2170）$的三体性质。在我们的形式主义中，我们还可以解释$ K^*（892）\ bar k^*（892）$的抑制衰减，如Besiii合作所示。此外，当可以提供更高的统计数据时，我们的结果对于阐明$ k（1460）$，$ k_1（1270）$和$ k_1（1400）$的属性可能很有用。
In this work we study the strong decays of $ϕ(2170)$ to final states involving the kaonic resonances $K(1460)$, $K_1(1270)$ and $K_1(1400)$, on which experimental data have recently been extracted by the BESIII Collaboration. The formalism developed here is based on interpreting $ϕ(2170)$ and $K(1460)$ as states arising from three-hadron dynamics, which is inspired by our earlier works. For $K_1(1270)$ and $K_1(1400)$ we investigate different descriptions, such as a mixture of states belonging to the nonet of axial resonances, or the former one as a state originating from the vector-pseudoscalar dynamics. The ratios among the partial widths of $K^+(1460)K^-$, $K^+_1(1400)K^-$ and $K^+_1(1270)K^-$ obtained are compatible with the experimental results, reinforcing the three-body nature of $ϕ(2170)$. Within our formalism, we can also explain the suppressed decay of $ϕ(2170)$ to $K^*(892) \bar K^*(892)$, as found by the BESIII Collaboration. Furthermore, our results can be useful in clarifying the properties of $K(1460)$, $K_1(1270)$ and $K_1(1400)$ when higher statistics data would be available.
