New evidence of CP Violation could help solve the matter–antimatter puzzle

In two new articles, the LHCb collaboration at the Large Hadron Collider (LHC) reports seeing evidence of CP violation in decays of baryons and in decays of beauty hadrons into charmonium particles, shedding light on these two pieces of the matter–antimatter puzzle. Experiments, including LHCb, have previously conducted searches for CP violation in baryons, by looking for differences in the way matter and antimatter baryons decay into other particles. But these searches have essentially come up empty handed so far.
