in 2012, we study the $J/\psi\rightarrow\gamma\eta^{\prime}\pi^{+}\pi^{-}$
process and observe a significant abrupt change in the slope of the
$\eta^{\prime}\pi^{+}\pi^{-}$ invariant mass distribution at the
proton-antiproton ($p\bar{p}$) mass ... | Phys. Rev. Lett. 117, 042002 (2016) | 10.1103/PhysRevLett.117.042002 |
2018-08-08T00:00:00 | Evidence of a resonant structure in the $e^+e^-\to π^+D^0D^{*-}$ cross section between 4.05 and 4.60 GeV | M. Ablikim, M. N. Achasov, S. Ahmed, M. Albrecht, A. Amoroso, F. F.

Cakir, A. Calcaterra, G. F. Cao, S. A. Cetin, J. Cha... | The cross section of the process $e^+e^-\to \pi^+D^0D^{*-}$ for
center-of-mass energies from 4.05 to 4.60~GeV is measured precisely using data
samples collected with the BESIII detector operating at the BEPCII storage
ring.
Two enhancements are clearly visible in the cross section around 4.23 and
4.40~GeV.
