Resumo

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. (AU)
