​CP violation in decays of neutral B mesons can occur in the interference between decay amplitudes with and without mixing. LHCb has new measurements in two of the "golden" CP violation analysis channels. The charmonium decays of B0 → ѱ KS0 with ѱ=J/ѱ, ѱ(2S) and Bs0→ J/ѱ 𝜙 are strongly dominated by the b → c cbar s transition, and have clean experimental signatures. Using the full Run2 data set recorded with the LHCb detector, the CKM angles β and φs are measured with the best precisions in single measurements to date. In this seminar, the latest results and the combination with previous measurements are presented.

Refreshments will be served at 10:30
