[ ACP(B0s→K–π+) = +0.27 ± 0.04 ± 0.01 ] [ ACP(B0→K+π–) = -0.080 ± 0.007 ± 0.003 ] The LHCb Collaboration has just submitted for publication a paper which sets an important milestone in the history of particle physics. A difference between properties of matter and antimatter, named CP violation by particle physicists, was discovered…
