1  Pole mass, width for a mass-,width-dependent Breit-Wigner fit to the mass spectrum recoiling against ${{\mathit K}_{{{S}}}^{0}}$ at center of mass energies between 4.628 and 4.699 GeV, with a significance of 4.6 $\sigma $.
2  Properties incompatible with a ${{\mathit q}}{{\overline{\mathit q}}}$ structure (exotic state). See the review on "Heavy Non-${{\mathit q}}{{\overline{\mathit q}}}$ Mesons."
3  From an amplitude analysis of the decay ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \phi}}{{\mathit K}^{+}}$ with a significance of 15 $\sigma $.
4  Pole mass, width for a mass-,width-dependent Breit-Wigner fit to the mass spectrum recoiling against ${{\mathit K}^{+}}$ at center of mass energies between 4.628 and 4.698 GeV, with a significance of 5.3 $\sigma $.
