Abstract
Considering the situation that a single chiral particle, η is initially emitted, we study the hidden-charm di-eta decays of the charmoniumlike state and the predicted charmonium , i.e., through the inetermediates and/or , and answer the important question of whether there exist isoscalar charmoniumlike structures in the and/or channels. Our results predict that there will be enhancement structures near , and thresholds for and near , and thresholds for in the distributions of , respectively. These peaks are accessible in future experiments, especially BESIII, Belle, BaBar, and the forthcoming BelleII.
