Charge-parity ($C\!P$) violation in the $b$-quark sector can be investigated by means of the time-integrated decay rates of beauty hadrons into various final states. $C\!P$ violation is a phenomenon that plays a crucial role in understanding the observed matter-antimatter asymmetry in the universe.
Several experimental efforts have been made at high-energy physics laboratories in the last decades aiming to measuring the $C\!P$-violating observables and the elements of the Cabibbo-Kobayashi-Maskawa matrix that describe the Standard Model (SM) and exploring any theoretical implication or hint for new physics beyond the SM. A better knowledge of all these ingredients will provide a strong contribution to unraveling the fundamental symmetries of particle physics and shedding light on the mysterious baryon asymmetry in the universe.
This report provides a comprehensive overview of time-integrated $C\!P$ violation in $b$-sector, analyzing some of the latest results achieved by the LHCb and Belle collaborations and discussing the future projections of these results.
