First observation of quantum correlations in and -even constrained pairs
BESIII Collaboration, M. Ablikim, M. N. Achasov +698
The study of meson pairs produced with quantum correlations gives direct access to parameters that are challenging to measure in other systems. In this Letter, the existence of qua…

Analyzing collision data corresponding to an integrated luminosity of collected at center-of-mass energies between 4.128 and 4.226~GeV with the BES…
Measurements of the branching fractions of the -wave charmonium spin-singlet state
BESIII Collaboration, M. Ablikim, M. N. Achasov +649
Based on events, we investigate four hadronic decay modes of the -wave charmonium spin-singlet state ($h=…
