Charmonium decay in the C3P0 Model

Abstract

In this work, we use the $C^3{P}_0$ model to calculate the decay widths of the low lying charmonium $J^{PC}=1^{--}$ states, nominally $J/\psi (1S)$ and $\psi (2S)$, in the following common channels: $\rho \pi$, $\omega \eta$, $\omega {\eta }^{\prime }$, $K^{\ast +}{K}^{-}$, $K^{\ast 0}{\bar{K}}^0$, $\varphi \eta$, $\varphi {\eta }^{\prime }$.
