CP Violation in B meson decays

Previous analysis performed by the group provided two new measurements of CP violation.

In October 2020 the first observation of time-dependent CP violation in Bs0 decays was announced. This discovery marks an important milestone in the history of particle physics as previous observations of CP violation were limited to the K0, D0 and B0 mesons and only the time-integrated CP violation was observed in Bs0 decays. The Bs0 meson decay into K+K- pairs as a function of the Bs0 meson decay time was studied in a simultaneous analysis with the other relevant B(s)0 h+h- decay modes
