1  One of two ${{\mathit K}_{{{1}}}}$ states reported by AAIJ 2021E. From an amplitude analysis of the decay ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \phi}}{{\mathit K}^{+}}$ with a significance of 4.5 $\sigma $.
2  From an amplitude analysis of the decay ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \phi}}{{\mathit K}^{+}}$ with a significance of 7.6 $\sigma $.
3  Superseded by AAIJ 2021E.
