Query: Predicted charged charmonium-like structures in the hidden-charm dipion
  decay of higher charmonia   In this work, we predict two charged charmonium-like structures close to the
$D^\ast\bar{D}$ and $D^\ast\bar{D}^\ast$ thresholds, where the Initial Single
Pion Emission mechanism is introduced in the hidden-charm dipion decays of
higher charmonia $\psi(4040)$, $\psi(4160)$, $\psi(4415)$ and charmonium-like
state Y(4260). We suggest BESIII to search for these structures in the
$J/\psi\pi^+$, $\psi(2S)\pi^+$ and $h_b(1P)\pi^+$ invariant mass spectra of the
$\psi(4040)$ decays into $J/\psi\pi^+\pi^-$, $\psi(2S)\pi^+\pi^-$ and
$h_b(1P)\pi^+\pi^-$. In addition, the experimental search for these structures
in the $J/\psi\pi^+$, $\psi(2S)\pi^+$ and $h_c(1P)\pi^+$ invariant mass spectra
of the $\psi(4260)$ hidden-charm dipion decays will be accessible at Belle and
BaBar.
