Using a sample of events accumulated with the BESIII detector, we analyze the decays ( or ) via the process $J/ψ…
Study of the electromagnetic Dalitz decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +640
We report the first measurement of the di-electron invariant mass dependent transition form factor in the electromagnetic Dalitz decay using $(10087 \pm 44) \ti…

Measurement of Born cross section of at GeV
BESIII Collaboration, M. Ablikim, M. N. Achasov +654
Using collision data collected with the BESIII detector at the BEPCII collider at thirty-two center-of-mass energies from 3.50 to 4.95 GeV, corresponding to an integrated…
