First Measurement of the Absolute Branching Fraction of
BESIII Collaboration, M. Ablikim, M. N. Achasov +691
We apply a tag-and-probe method to precisely measure the absolute branching fraction of the decay with the BESIII experiment at BEPCII. Starting with a large initial s…

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…
