Scientists with the LHCb experiment, located at the Large Hadron Collider near Geneva, have found hints of CP violation in the decays of a lambda-b baryon. When the lambda-b baryon decays, particles produced by the decay speed away at different angles and momenta for matter and antimatter versions of the baryon, the scientists report online September 16 at
Specifically, the scientists detected differences in spatial orientation of decay products of a class of matter and antimatter particles called Lambda-b baryons.
