Abstract

We present updated measurements of time-dependent CP asymmetries in fully reconstructed neutral B decays containing a charmonium meson. The measurements reported here use a data sample of (465 +/- 5)x10(6) Upsilon(4S)-> B<overline>B</overline> decays collected with the BABAR detector at the PEP-II asymmetric energy e(+)e(-) storage rings operating at the SLAC National Accelerator Laboratory. The time-dependent CP asymmetry parameters measured from J psi K-S(0), J psi K-L(0), psi(2S)K-S(0), eta K-c(S)0, chi K-c1(S)0, and J/psi K-*(892)(0) decays are: C-f=0.024 +/- 0.020(stat)+/- 0.016(syst) and -eta S-f(f)=0.687 +/- 0.028(stat)+/- 0.012(syst).
