摘要：

We propose the initial single chiral particle emission mechanism, with which the hidden-charm dikaon decays of higher charmonia and charmoniumlike states are studied. Calculating the distributions of differential decay width, we obtain the line shape of the J/psi K+ invariant mass spectrum of psi(i) -> J/psi K+K-, where psi(i) = psi(4415), Y(4660), and psi(4790). Our numerical results show that there exist enhancement structures with both hidden-charm and open-strange channels, which are near the D (D) over bar*(s)/D*(D) over bar (s) and D*(D) over bar*(s)/(D) over bar *D*(s) thresholds. These charged charmoniumlike structures predicted in this Letter can be accessible in future experiments, especially BESIII, BelleII, and SuperB.
