Strong and electromagnetic amplitudes, direct and isospin asymmetries in the decays
BESIII Collaboration, M. Ablikim, M. N. Achasov +766
Using annihilation data collected at 26 center-of-mass energy points between 3000.00 and with the BESIII detector, corresponding to a total integrated…

Unexpected large relative strong phase and search for isospin breaking and asymmetries in $J/Ï\to K^*(892)\bar K
BESIII Collaboration, M. Ablikim, M. N. Achasov +766
Using a direct scan of 26 energy points near the resonance, we perform the first measurement of the relative phase between the strong and electromagnetic ampli…
