英文摘要Based on the updated data of charmoniumlike state Y(4220) reported in the hidden-charm channels of the e(+)e(-) annihilation, we propose a 4S-3D mixing scheme to categorize Y(4220) into the J/psi family. We find that the present experimental data can support this charmonium assignment to Y(4220). Thus, Y(4220) plays a role of a scaling point in constructing higher charmonia above 4 GeV. To further test this scenario, we provide more abundant information on the decay properties of Y(4220), and predict its charmonium partner psi(4380), whose evidence is found by analyzing the e(+)e(-) -> psi(3686)pi(+)pi(-) data from BESIII. If Y(4220) is indeed a charmonium, we must face how to settle the established charmonium psi(4415) in the J/psi family. In this work, we may introduce a 5S-4D mixing scheme, and obtain the information of the resonance parameters and partial open-charm decay widths of psi(4415), which do not contradict the present experimental data. Additionally, we predict a charmonium partner psi(4500) of psi(4415), which can be accessible at future experiments, especially, BESIII and BelleII. The studies presented in this work provide new insights to establish the higher charmonium spectrum.
