Sumario: | Precision measurements of beauty hadron decays constitute excellent probes ofthe Standard Model and an important way to look for physics beyond. Inparticular, new sources of Charge-Parity violation are searched for, given theinconsistency between the matter/anti-matter asymmetry observed in the Universeand the small amount of Charge-Parity violation that the Standard Model canaccommodate. This document reviews the state-of-the-art measurements of Charge-Parity violation in beauty hadron decays performed by the experiments at theLarge Hadron Collider, mostly the LHCb experiment. The latest measurements ofthe $γ$, $β$ and $β_s$ angles of the Cabbibo-Kobayashi-Maskawa matrix are presented, aswell as recent studies of Charge-Parity violation in the $B^0_{(s)} → hh'$ , $B_{s}^{0} → (K^+ π^−)(K^−π^+)$ and $B^+ → D_{(s)}^{+} \overline D^0$ decays. Finally, a new measurement of Charge-Parity asymmetries in beauty-baryon decays is also presented. |
