Observation of charge-parity symmetry breaking in baryon decays
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1136
The Standard Model of particle physics-the theory of particles and interactions at the smallest scale-predicts that matter and antimatter interact differently due to violation of t…

Test of lepton flavour universality with decays
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1128
Lepton flavour universality in rare transitions is tested for the first time using meson decays. The measurements are performed using collision data c…

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…
