Partial decay widths of φ(2170) to kaonic resonances

In this work, we study the strong decays of 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 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-, K-1(+)(1400)K-, and K-1(+)(1270)K- obtained arc compatible with the experimental results, reinforcing the three-body nature of phi(2170). Within our formalism, we can also explain the suppressed decay of phi(2170) to K*(892)(K) over bar*(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.

Automated summary

This study investigates the strong decays of phi(2170) to final states involving kaonic resonances, based on experimental data extracted by the BESIII Collaboration. The formalism developed interprets phi(2170) and K(1460) as states arising from three-hadron dynamics and explores different descriptions for K-1(1270) and K-1(1400). The results support the three-body nature of phi(2170) and provide insights into the properties of K(1460), K-1(1270), and K-1(1400) for future studies with higher statistics data.
