title = "Observation of CP violation in two-body B(s)0 -meson decays to charged pions and kaons",
abstract = "The time-dependent CP asymmetries of B0? p+p- and Bs0? K+K- decays are measured using a data sample of pp collisions corresponding to an integrated luminosity of 1.9 fb-1, collected with the LHCb detector at a centre-of-mass energy of 13 TeV. The results are Cpp=-0.311±0.045±0.015,Spp=-0.706±0.042±0.013,CKK=0.123±0.034±0.015,SKK=0.164±0.034±0.014,AKK?G=-0.83±0.05±0.09, where the first uncertainties are statistical and the second systematic. The same data sample is used to measure the time-integrated CP asymmetries of B0? K + p- and Bs0?K-p+ decays and the results areACPB0=-0.0824±0.0033±0.0033,ACPBs0=0.236±0.013±0.011. All results are consistent with earlier measurements. A combination of LHCb measurements provides the first observation of time-dependent CP violation in Bs0 decays.
