Search for the charged lepton flavor violating decay
M. Ablikim, M. N. Achasov, P. Adlarson +708
Based on events collected at the center-of-mass energy ~GeV with the BESIII detector, we search for the charged lepton fla…
First observation of the decay
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1072
The decay is observed for the first time using proton-proton collision data collected by the LHCb experiment at a center-of-mass energy of …
Evidence for decays
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1132
The first evidence for the decay is obtained using proton-proton collision data collected by the LHCb experiment, corresponding to an i…
Measurement of the multiplicity dependence of $\mitΥ$ production ratios in collisions at TeV
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1132
The $\mitÎ¥(\mathrm{2}S)$ and $\mitÎ¥(\mathrm{3}S)$ production cross-sections are measured relative to that of the $\mitÎ¥(\mathrm{1}S)$ meson, as a function of charged-particle mu…
Measurement of meson production in fixed-target Ne collisions at = 68.5 GeV
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1132
The first measurement of meson production in fixed-target Ne collisions at GeV is presented. The mesons are reconstructed in their $K^…
First evidence for direct CP violation in beauty to charmonium decays
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1131
The asymmetry and branching fraction of the CKM-suppressed decay are precisely measured relative to the favoured decay $B^+\!\to…
