Abstract
Analysing a data sample corresponding to an integrated luminosity of 3 fb−1 of pp collisions collected by the LHCb detector at the LHC CP violation in B0 → J/ψK0S and B0s → J/ψK0S is measured. The results S(B0→ J/ψK0S) = 0.731 ± 0.035 (stat) ± 0.020 (syst), C(B0→ J/ψK0S) = −0.038 ± 0.032 (stat) ± 0.005 (syst) are consistent with the current world averages and with the Standard Model expectations. In B0s → J/ψK0S the results AΔΓ(B0s → J/ψK0S) = 0.49 ± 0.77 0.65 (stat) ± 0.06 (syst), S(B0s → J/ψK0S) = −0.08 ± 0.40 (stat) ± 0.08 (syst), C(B0s → J/ψK0S) = −0.28 ± 0.41 (stat) ± 0.08 (syst) reflect the first determination of these CP observables paving a new way towards the control of penguin pollutions in the determination of sin 2β.
