Search for the decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +506
Using 6.32 fb of electron-positron collision data recorded by the BESIII detector at center-of-mass energies between 4.178 and 4.226~GeV, we present the first search for the…

Measurement of the Born cross sections for at center-of-mass energies between and GeV
BESIII Collaboration, M. Ablikim, M. N. Achasov +487
The Born cross sections for the process at different center-of-mass energies between and GeV are reported with improved precision fro…
