Using collision data collected with the BESIII detector at the BEPCII collider corresponding to an integrated luminosity of 5.2 at center-of-mass energies ($…
Measurements of the branching fractions for the semi-leptonic decays , , and
M. Ablikim, M. N. Achasov, S. Ahmed +439
By analyzing 482 pb of collision data collected at the center-of-mass energy GeV with the BESIII detector, we measure the %absolute branching fracti…
Observation of the decay
BESIII Collaboration, M Ablikim, M N Achasov +428
We report the first observation of the decay , based on data obtained in annihilations with an integrated luminosity of 567~pb at…
Measurement of higher-order multipole amplitudes in with and search for the transition
M. Ablikim, M. N. Achasov, X. C. Ai +424
Using 106~million events collected with the BESIII detector, we measure multipole amplitudes for the decay beyond the dominant elect…
