Partial decay widths of ϕ(2170) to kaonic resonances

subject

description

In this work, we study the strong decays of $\ensuremath{\phi}(2170)$ 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 $\ensuremath{\phi}(2170)$ 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 ${K}^{+}(1460){K}^{\ensuremath{-}}$, ${K}_{1}^{+}(1400){K}^{\ensuremath{-}}$, and ${K}_{1}^{+}(1270){K}^{\ensuremath{-}}$ obtained are compatible with the experimental results, reinforcing the three-body nature of $\ensuremath{\phi}(2170)$. Within our formalism, we can also explain the suppressed decay of $\ensuremath{\phi}(2170)$ to ${K}^{*}(892){\overline{K}}^{*}(892)$, 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 are available.
