1  From an amplitude analysis of the decay ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \phi}}{{\mathit K}^{+}}$ with a significance of 17 $\sigma $.
2  From a 1D fit to the ${{\mathit J / \psi}}{{\mathit \phi}}$ mass distribution with a significance of 5.3 $\sigma $. The identification of this structure as the ${{\mathit \chi}_{{{c0}}}{(4700)}}$ needs confirmation.
3  From an amplitude analysis of the decay ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \phi}}{{\mathit K}^{+}}$ with a significance of 5.6 $\sigma $.
4  Superseded by AAIJ 2021E.
