(Vector) Glueballs and Charmonium Decay Revisited

Abstract

From the $0^{++}$ glueball candidate we argue that the $1^{--}$ glueball $O$ to be near in mass to $J/\psi$. This is supported by the recent null search for ${\psi }^{\prime }\to \rho \pi ,K^{\ast }\bar{K}$, while absence of distortion in the energy scan of $J/\psi \to \rho \pi$ indicates that ${\Gamma }_O\gg {\Gamma }_{J/\psi }$. $O$ may also play a role in the OZI violating $\bar{p}p\to \varphi \gamma ,\varphi \pi$ production puzzle.
