Study of and in the decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +666
We perform an amplitude analysis of the decay and measure its absolute branching fraction to be $(1.016 \pm 0.013_{\text {stat.}} \pm 0.014_{\text {syst.}})\%…

Measurements of absolute branching fractions of decays
BESIII Collaboration, M. Ablikim, M. N. Achasov +697
Using an sample of collected at the center-of-mass energy 3.773 GeV with the BESIII detector, we report measurements of several four-body h…
