The mass of ${{\mathit \omega}{(1420)}}$ is fixed to the PDG 2018 value of 1420 MeV. Fixing also the width of ${{\mathit \omega}{(1420)}}$ to the PDG 2018 value of 220 MeV results in $94$ $\pm13$ MeV measurement. 2  Could also be ${{\mathit \rho}{(1700)}}$. Branching ratio ${{\mathit J / \psi}}$ $\rightarrow$ ${{\mathit X}}{{\mathit \pi}^{0}}$ $\rightarrow$ ${{\mathit K}^{+}}{{\mathit K}^{-}}{{\mathit \pi}^{0}}$ = ($5.3$ $\pm0.3$ ${}^{+0.6}_{-0.5}$) $ \times 10^{-5}$. 3  From a fit of the interfering ${{\mathit \omega}{(1420)}}$ and ${{\mathit \omega}{(1650)}}$ with a relative phase of ${{\mathit \pi}}$ and other parameters floating. 4  From a fit with contributions from ${{\mathit \omega}{(1420)}}$, ${{\mathit \omega}{(1650)}}$, and ${{\mathit \phi}{(1680)}}$. 5  From a fit with contributions from ${{\mathit \omega}{(782)}}$, ${{\mathit \phi}{(1020)}}$, ${{\mathit \omega}{(1420)}}$, and ${{\mathit \omega}{(1650)}}$. See ACHASOV 2020A for a further analysis of the ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}{{\mathit \pi}^{0}}$ data. 6  From the combined fit of ANTONELLI 1992 , ACHASOV 2001E, ACHASOV 2002E, and ACHASOV 2003D data on the ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}{{\mathit \pi}^{0}}$ and ANTONELLI 1992 on the ${{\mathit \omega}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ final states. Supersedes ACHASOV 1999E and ACHASOV 2002E. 7  Using results of CORDIER 1981 and preliminary data of DOLINSKY 1991 and ANTONELLI 1992 . 8  Using the data of AKHMETSHIN 2000D and ANTONELLI 1992 . The ${{\mathit \rho}}{{\mathit \pi}}$ dominance for the energy dependence of the ${{\mathit \omega}{(1420)}}$ and ${{\mathit \omega}{(1650)}}$ width assumed. 9  From a fit to two Breit-Wigner functions and using the data of DOLINSKY 1991 and ANTONELLI 1992 . 10  From the combined fit of the ${{\mathit \rho}}{{\mathit \pi}}$ and ${{\mathit \omega}}{{\mathit \pi}}{{\mathit \pi}}$ final states.
