1  Obtained from the full amplitude analysis. Parameterized with the relativistic Breit-Wigner line shape.
2  ${{\mathit \omega}}{{\mathit J / \psi}}$ threshold enhancement fitted as an S-wave Breit-Wigner resonance.
3  Not distinguished from the ${{\mathit \chi}_{{c2}}{(3930)}}$.
4  Could also be ${{\mathit X}{(3940)}}$. Significance 3.1$\sigma $. Fit with additional resonance at $3963.7$ $\pm5.7$ MeV, significance 3.4$\sigma $.
