CERN physicists observed CP violation in baryons

CERN's LHCb collaboration has observed charge-parity (CP) violation in baryons for the first time, a finding consistent with the Standard Model of particle physics. This discovery could help constrain theories beyond the Standard Model. The experiment analyzed the decays of beauty baryons and antibaryons produced in proton collisions, finding an asymmetry consistent with CP violation. This result, with a 5.2σ significance, confirms the Standard Model's predictions for this phenomenon. This observation, while consistent with the Standard Model, could provide a path to new physics by potentially constraining extensions to the model. Further data from the LHC's ongoing run may offer more precise measurements.
