From the fit to the BABAR data of LEES 2013Q assuming a coherent sum of a single Breit-Wigner resonance and a nonresonant contribution. The resonance significance is 3.5 ${{\mathit \sigma}}$.

From the fit to the BABAR data of LEES 2013Q and BESIII data of ABLIKIM 2019L assuming a coherent sum of a single Breit-Wigner resonance and a nonresonant contribution.

Could also be another state. Seen in ${{\mathit J / \psi}}$ decay with branching ratio ${{\mathit J / \psi}}$ $\rightarrow$ ${{\mathit X}}{{\mathit \pi}^{0}}$ $\rightarrow$ ${{\mathit K}^{+}}{{\mathit K}^{-}}{{\mathit \pi}^{0}}$ = ($6.7$ $\pm1.1$ ${}^{+2.2}_{-1.8}$) $ \times 10^{-6}$.

The observed structure can be due to both the ${{\mathit \phi}{(2170)}}$ and ${{\mathit \rho}{(2150)}}$.

Using the GOUNARIS 1968 parametrization of the pion form factor leaving the masses and widths of the ${{\mathit \rho}{(1450)}}$, ${{\mathit \rho}{(1700)}}$, and ${{\mathit \rho}{(2150)}}$ resonances as free parameters of the fit.
