Abstract
The LHCb detector is a dedicated heavy flavour experiment operating at the Large Hadron Collider designed to pursue an extensive study of CP violation in the beauty and charm sectors. In the first part of this contribution, important milestones towards the measurement of CP violation in the beauty sector using B ± and B 0 s decays are presented. In the second part, highlights of the searches of CP violation in the charm sector are reported.
Highlights
The LHCb detector is a single-arm spectrometer designed to test the CKM paradigm of flavour structure and CP violation
The CP violating phase φs can be measured through the interference between the direct decay of B0s → J/ψφ and the decay via B0s − B0s oscillation
The results obtained for the CP violating phase φs, the decay width Γs and the mean decay width difference ΔΓs are φs = −0.001 ± 0.101 ± 0.027 rad, Γs = 0.6580 ± 0.0054 ± 0.0066 ps−1, ΔΓs = 0.116 ± 0.018 ± 0.006 ps−1
Summary
The LHCb detector is a single-arm spectrometer designed to test the CKM paradigm of flavour structure and CP violation. In this document six LHCb measurements of CP violation in the beauty and charm sectors are reviewed. A detailed analysis of the B± → DK± decay, sensitive to the CKM angle γ, is presented in Sec.. In Sec. three measurements of charm hadron decays are presented, including a first observation of CP violation in the charm sector
