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

TL;DR

This paper predicts charged charmoniumlike structures near specific thresholds in the decay spectra of Y(4360), suggesting experimental verification by BESIII, Belle, and BelleII.

Contribution

It introduces a novel prediction of charged charmoniumlike structures in Y(4360) decays using the Initial Single Pion Emission mechanism.

Findings

Charged structures near D D* and D* D* thresholds identified.

Predicted structures appear in J/ψπ+, ψ(2S)π+, and h_c(1P)π+ spectra.

Encourages experimental searches at BESIII, Belle, and BelleII.

Abstract

Studying the hidden-charm dipion decays of the charmoniumlike state Y(4360), we show that there exist charged charmoniumlike structures near $D\bar{D}^*$ and $D^*\bar{D}^*$ 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.
