The latest measurements of the CP -violation observables in the charmless two-body decays of B0 and B0s mesons are reported. The analysis involves the data collected by the LHCb experiment at a centre-of-mass energy of 13 TeV, corresponding to a total integrated luminosity of 1.9 fb−1. The combination of these results with the previous determinations by LHCb (additional 3.1 fb−1) provides the most precise measurements of these quantities by a single experiment. In particular, time-dependent CP violation is observed for the first time in the B0s sector.

Abstract
The latest measurements of the CP -violation observables in the charmless two-body decays of B0 and B0s mesons are reported. The analysis involves the data collected by the LHCb experiment at a centre-of-mass energy of 13 TeV, corresponding to a total integrated luminosity of 1.9 fb−1. The combination of these results with the previous determinations by LHCb (additional 3.1 fb−1) provides the most precise measurements of these quantities by a single experiment. In particular, time-dependent CP violation is observed for the first time in the B0s sector.| File | Dimensione | Formato | |
