Predictions of charged charmonium-like structures with hidden-charm and open-strange channels

Abstract

We propose the initial single chiral particle emission mechanism, with which the hidden-charm di-kaon decays of higher charmonia and charmonium-like states are studied. Calculating the distributions of differential decay width, we obtain the line shape of the $J/\psi K^{+}$ invariant mass spectrum of ${\psi }_i\to J/\psi K^{+}{K}^{-}$, 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 decays, which are near the $D{\bar{D}}_s^{\ast }/D^{\ast }{\bar{D}}_s$ and $D^{\ast }{\bar{D}}_s^{\ast }/{\bar{D}}^{\ast }{D}_s^{\ast }$ thresholds. These charged charmonium-like structures predicted in this Letter can be accessible in future experiments, especially BESIII, BelleII, and SuperB.
