Amplitude analysis and branching fraction measurement of the decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +612
Using 2.93 of collision data collected with the BESIII detector at the center-of-mass energy 3.773\,GeV, we perform the first amplitude analysis of the deca…

Determination of U-spin breaking parameters with an amplitude analysis of the decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +605
We present a study of the resonant structure of the decay , using quantum-correlated data produced at GeV. The data sampl…

Search for the weak radiative decay at BESIII
BESIII Collaboration, M. Ablikim, M. N. Achasov +567
The Cabibbo-allowed weak radiative decay has been searched for in a sample of pairs produced in annihilations, corresponding to an i…
