| contents | In this work, we investigate the mass spectra of excited charmonia employing a nonrelativistic potential model with screening effect, and analyze their two-body strong decay, two-photon decay, leptonic decay, and hadronic transitions. Especially, we find that the newly observed resonances $X(4160)$, $Y(4500)$, and $Y(4710)$ can be identified as $3^3P_0$, $3^3D_1$, and $4^3D_1$ states, respectively. We also predict the masses and the widths of higher excited states in the charmonia family. |
