Novel charged charmoniumlike structures in the hidden-charm dipion decays of Y(4360)

Abstract

Studying the hidden-charm dipion decays of the charmoniumlike state Y(4360), we show that there exist charged charmoniumlike structures near $D{\bar{D}}^{\ast }$ and $D^{\ast }{\bar{D}}^{\ast }$ thresholds in the $J/\psi {\pi }^{+}$, $\psi (2S){\pi }^{+}$ and $h_c(1P){\pi }^{+}$ invariant mass spectra of the corresponding hidden-charm dipion decays of Y(4360) using the {\it{Initial Single Pion Emission} mechanism}. We suggest to do further experimental study on these predicted charged enhancement structures, especially by BESIII, Belle, and the forthcoming BelleII.
