Abstract

The strong decays of the radially excited $\psi (3^3S_1)$ state are studied within the $$^3P_0$$ model. As a believed $\psi (3^3S_1)$ , some strong decay widths and relevant ratios of $\psi (4040)$ are calculated in the model. In a similar way, as a possible $\psi (3^3S_1)$ , the same strong decay widths and relevant ratios of $$Y(4008)$$ are presented. Our study indicates that is hard to be identified with a $\psi (3^3S_1)$ charmonium once it is confirmed under the $D^*\bar{D}^*$ threshold, but it is possibly a $\psi (3^3S_1)$ charmonium once it is confirmed above the $D^*\bar{D}^*$ threshold by experiment.
