Abstract
The time-dependent asymmetry in decays is measured using collision data at , corresponding to an integrated luminosity of , collected with the LHCb detector. The decay-time distribution is characterized by the decay widths and of the light and heavy mass eigenstates of the system and by a -violating phase . In a sample of 27 617 decays, where the dominant contribution comes from decays, these parameters are measured to be , , and , corresponding to the single most precise determination of , , and . The result of performing a combined analysis with decays gives , , and . All measurements are in agreement with the Standard Model predictions.
