Search for the charged lepton flavour violating decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +765
Based on events collected in collisions at GeV with the BESIII detector, we present a search for the charged lepton flavou…
Searches for charged-lepton-flavor violation in decays
Belle, Belle II Collaborations, : +425
We report the first searches for charged-lepton-flavor violation in decays of ( and ) to a pair of charged leptons using 158 million decays collect…
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…
Measurement of time-dependent violation parameters in decays at Belle and Belle II
Belle, Belle II Collaborations, : +416
We perform a measurement of time-dependent violation parameters in decays using a dataset of approximately and $521 \times 10…
Improved measurement of Born cross sections for and ( = 0, 1, 2) at Belle and Belle II
Belle, Belle II Collaborations, : +424
We study the processes and ( = 0, 1, 2) at center-of-mass energies from 10.73 to 11.02 GeV using a $142.5\,\mathr…
