Predictions of charged charmonium-like structures with hidden-charm and
open-strange channel    [PDF]

Dian-Yong Chen, Xiang Liu, Takayuki Matsuki

We propose the initial single chiral particle emission (ISChE) 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, which are near the $D_s\bar{D}^*/\bar{D}_s^*D$ and $D^*\bar{D}_s^*/\bar{D}^*D_s^*$ thresholds. These charged charmonium-like structures predicted in this paper can be accessible at future experiment, especially BESIII, BelleII and SuperB.
