$C\!P$ violation in beauty and charm quarks at LHCb

The LHCb experiment has been reporting remarkable $C\!P$-violation (CPV) measurements concerning the sectors of $b$ and $c$ quarks. Recently, the new measurements of time-integrated CPV with $D^0\to K^+ K^-$ decays led to the first evidence ($3.8σ$) of CPV in a single charmed decay. The first search for CPV in the $D_{(s)}^+\to K^+K^+K^-$ decays was executed. The knowledge of the CKM parameter $γ$ was improved by new results; the current combination of the LHCb measurements is: $\left(63.8^{+3.5}_{-3.7}\right)^\circ$. The study of $B_s^0\toϕϕ$ decays resulted in the most precise measurement of time-dependent CPV in any penguin-dominated $B$ meson decay. All the results are consistent with the Standard-Model predictions.

$C\!P$ violation in $B$ mesons

This proceeding reports a selection of recent experimental results concerning $C\!P$ violation in the sectors of $B^0$ and $B^\pm$ mesons. They were published within the last two years by the Belle, Belle II and LHCb collaborations. The first set of measurements is related to the determination of the angles of the Unitarity Triangle. The second is connected to another crucial test of the SM: the isospin sum rule of $B \to Kπ$ decays. Thirdly, studies of $C\!P$ violation in the decays charged $B$ mesons to charmless three-body final states are presented. Finally, prospects for the future experimental upgrades of this sector are summarised.
