title = "Measurement of CP asymmetries in two-body B (s)0 -meson decays to charged pions and kaons",
abstract = "The time-dependent CP asymmetries in B0→π+π- and Bs0→K+K- decays are measured using a data sample of p p collisions corresponding to an integrated luminosity of 3.0 fb-1, collected with the LHCb detector at center-of-mass energies of 7 and 8 TeV. The same data sample is used to measure the time-integrated CP asymmetries in B0→K+π- and Bs0→π+K- decays. The results are Cπ+π-=-0.34±0.06±0.01, Sπ+π-=-0.63±0.05±0.01, CK+K-=0.20±0.06±0.02, SK+K-=0.18±0.06±0.02, AK+K-ΔΓ=-0.79±0.07±0.10, ACPB0=-0.084±0.004±0.003, and ACPBs0=0.213±0.015±0.007, where the first uncertainties are statistical and the second systematic. Evidence for CP violation is found in the Bs0→K+K- decay for the first time.",
