We present updated measurements of time-dependent CP asymmetries in fully-reconstructed neutral B decays to several CP eigenstates containing a charmonium meson. The measurements use a data sample of (383 +/- 4) x 10(6) Y (4S) -> B (B) over bar decays collected with the BABAR detector at the PEP-II B factory. We determine sin2 beta = 0.714 +/- 0.032(stat) +/- 0.018(syst) and |lambda| = 0.952 +/- 0.022(stat) +/- 0.017(syst).

Abstract

We present updated measurements of time-dependent CP asymmetries in fully-reconstructed neutral B decays to several CP eigenstates containing a charmonium meson. The measurements use a data sample of (383 +/- 4) x 10(6) Y (4S) -> B (B) over bar decays collected with the BABAR detector at the PEP-II B factory. We determine sin2 beta = 0.714 +/- 0.032(stat) +/- 0.018(syst) and |lambda| = 0.952 +/- 0.022(stat) +/- 0.017(syst).
