Charmonium decay in the C3P0 Model
In this work, we use the $C^3P_{\,0}$ model to calculate the decay widths of the low lying charmonium $J^{PC}=1^{--}$ states, nominally $J/ψ(1S)$ and $ψ(2S)$, in the following common channels: $ρ\,π$, $ω\,η$, $ω\,η^\prime$, $K^{\ast +}\,K^-$, $K^{\ast 0}\,\bar{K}^0$, $ϕ\,η$, $ϕ\,η^\prime$.
