Measurement of the singly Cabibbo-suppressed decay with Deep Learning
BESIII Collaboration, M. Ablikim, M. N. Achasov +689
Using fb of collision data collected with the BESIII detector at center-of-mass energies from 4.600 to 4.699 GeV, we report a measurement of the singly Cabibb…

Search for the reaction channel and the isospin partner of the at center-of-mass energies GeV
BESIII Collaboration, M. Ablikim, M. N. Achasov +693
We search for the reaction channel in a data sample with center-of-mass energies from 4.226 to 4.950~GeV, which was collected by the BESIII detector operating…
