First Measurement of the Decay Dynamics in the Semileptonic Transition of the into the Axial-vector Meson
BESIII Collaboration, M. Ablikim, M. N. Achasov +677
Using data taken at the center-of-mass energy of 3.773 GeV with the BESIII detector, corresponding to an integrated luminosity of 20.3 fb, we report the first measu…
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) \…
Observation of the charmonium decay in
BESIII Collaboration, M. Ablikim, M. N. Achasov +662
Using events collected with the BESIII detector at the BEPCII collider, the decay in is observed. We determin…
Measurement of Branching Fractions for and
BESIII Collaboration, M. Ablikim, M. N. Achasov +611
Based on 4.5 fb of collision data accumulated at center-of-mass energies between and with the BESIII detector, we me…
