${{\boldsymbol \psi}{(4230)}}$ $I^G(J^{PC})$ = $0^-(1^{- -})$

was ${{\mathit X}{(4230)}}$
This state shows properties different from a conventional ${{\mathit q}}{{\overline{\mathit q}}}$ state. A candidate for an exotic structure. See the review on non- ${{\mathit q}}{{\overline{\mathit q}}}$ states. Enhancement reported by ABLIKIM 2015C in ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit \omega}}{{\mathit \chi}_{{c0}}}$ at $\sqrt {s }$ = $4.23 - 4.26$ GeV at 9$\sigma $ significance. Lineshape found to be inconsistent with origination from ${{\mathit \psi}{(4260)}}$. Needs confirmation.
