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…
Updated measurement of the branching fraction of
BESIII Collaboration, M. Ablikim, M. N. Achasov +703
Using a dataset of 7.33 fb of annihilation data collected with the BESIII detector at center-of-mass energies from 4.128 to 4.226 GeV, we report an updated measure…
Observation of a threshold enhancement in the spectrum in decays
BESIII Collaboration, M. Ablikim, M. N. Achasov +677
The BESIII experiment analyzed over 2.7 billion ψ(3686) decays and observed a clear resonance-like enhancement near the π⁺π⁻ mass threshold in ψ(3686)→π⁺π⁻J/ψ decays, measuring its…
First measurement of the cross sections for at from 4.396 to 4.951 GeV
BESIII Collaboration, M. Ablikim, M. N. Achasov +701
Using collision data at 19 center-of-mass energies ranging from to corresponding to a total integrated luminosity of coll…
