Abstract

In this work, we predict two charged charmonium-like structures close to the D^∗D and D^∗D^∗ thresholds, where the Initial Single Pion Emission mechanism is introduced in the hidden-charm dipion decays of higher charmonia ψ(4040), ψ(4160), ψ(4415) and charmonium-like state Y(4260). We suggest BESIII to search for these structures in the J/ψπ⁺, ψ(2S)π⁺ and h_b(1P)π⁺ invariant mass spectra of the ψ(4040) decays into J/ψπ⁺π^-, ψ(2S)π⁺π^- and h_b(1P)π⁺π^-. In addition, the experimental search for these structures in the J/ψπ⁺, ψ(2S)π⁺ and h_c(1P)π⁺ invariant mass spectra of the ψ(4260) hidden-charm dipion decays will be accessible at Belle and BaBar.
