| 英文摘要 | Considering the situation that a single chiral particle, eta is initially emitted, we study the hidden- charm di- eta decays of the charmoniumlike state Y(4660) and the predicted charmonium Psi(4790), i.e., Y(4660)/Psi(4790) -> J/Psi eta eta through the inetermediates eta[D-(*)(D) over bar ((*))] and/or eta[D-s(+(*))+ D-s(-(*))] , and answer the important question of whether there exist isoscalar charmoniumlike structures in the D-(*)(D) over bar ((*)) and/or Ds+(*)Ds-(*) channels. Our results predict that there will be enhancement structures near D (D) over bar (*), D-*(D) over bar (*) and D-s(*)(D) over bar (*)(s) thresholds for Y(4660) and near D-*(D) over bar (*), D-s(D) over bar (*)(s) and D-s(*)(D) over bar (*)(s) thresholds for psi(4790) in the M-max (J/psi eta) distributions of Y(4660)/psi(4790) -> eta eta J/psi, respectively. These peaks are accessible in future experiments, especially BESIII, Belle, BaBar, and the forthcoming BelleII. |
