${{\mathit \psi}{(4230)}}$

$I^G(J^{PC})$ = $0^-(1^{- -})$ 

also known as ${{\mathit Y}{(4230)}}$; was ${{\mathit \psi}{(4260)}}$
The original ${{\mathit \psi}{(4260)}}$ (also known as ${{\mathit Y}{(4260)}}$) was observed by AUBERT,B 2005I as a peak in the energy dependence of the ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}{{\mathit J / \psi}}$ cross section and was confirmed by HE 2006B, YUAN 2007, LEES 2012AC, and LIU 2013B in the same process. A higher-statistics analysis by ABLIKIM 2017B revealed an asymmetry in the cross section and resulted in a shift of the peak position to a lower mass. The ${{\mathit \psi}{(4260)}}$ was therefore renamed ${{\mathit \psi}{(4230)}}$. The energy-dependent cross sections for ${{\mathit e}^{+}}{{\mathit e}^{-}}$ to other channels also exhibit peaks in the same mass region. The parameters corresponding to those peaks are also listed here, but the number of states in this region remains to be determined. For details see the review on "Spectroscopy of mesons containing two heavy quarks."
