Improved measurements of the coherence factors and strong-phase differences in and with quantum-correlated decays
BESIII Collaboration, M. Ablikim, M. N. Achasov +680
Improved measurements of the coherence factors and strong-phase differences in and decays are reported, using quantum-correlated pai…

Amplitude analysis and branching fraction measurement of the decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +703
An amplitude analysis of the decay is performed to determine the relative magnitudes and phases of different intermediate processes. The analysis uses $e^+e…
