Measurement of the time-dependent CP asymmetry in B → J/ψ K decays
This Letter reports a measurement of the CP violation observables S and C in the decay channel B → J/ψ K performed with 1.0 fb of pp collisions at √s = 7 TeV collected by the LHCb experiment. The fit to the data yields S J/ψ K0 S = 0.73 ± 0.07 (stat) ± 0.04 (syst) and C = 0.03 ± 0.09 (stat...
