Description
We have recently studied the strong decays of φ(2170) to final states involving the kaonic resonances K(1460), K1(1270) and K1(1400), on which experimental data have been extracted by the BESIII Collaboration. The formalism developed is based on interpreting φ(2170) and K(1460) as states arising from three-hadron dynamics. For K1(1270) and K1(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−, K1+(1400)K− and K1+(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)K ̄∗(892), as found by the BESIII Collaboration. Furthermore, our results can be useful in clarifying the properties of K(1460), K1(1270) and K1(1400) when higher statistics data would be available.
