Observation of $e^{+}{e}^{-}\to {\chi }_{c0}\omega$ and missing higher charmonium $\psi (4S)$

Abstract

Stimulated by the recent BESIII observation of a new resonance in $e^{+}{e}^{-}\to \omega {\chi }_{c0}$ and by the fact that this state is consistent with our predicted $\psi (4S)$, in this work we estimate the meson loop contribution to $\psi (4S)\to \omega {\chi }_{c0}$. The evaluation indicates that our theoretical estimate can overlap with the experimental data in a reasonable parameter range. This fact shows that introduction of the missing higher charmonium $\psi (4S)$ provides a possible explanation to the recent BESIII observation. The upper limit of a branching ratio of $\psi (4S)\to \eta J/\psi$ is also predicted as $1.9\times 10^{-3}$, which can be further tested by BESIII, Belle and forthcoming BelleII.
