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)×106 Υ(4S)→BB¯ decays collected with the BABAR detector at the PEP-II B factory. The time-dependent CP asymmetry parameters measured from J/ψK0S, J/ψK0L, ψ(2S)K0S, χc1K0S, ηcK0S, and J/ψK∗0 decays are
Cf=0.026±0.020(stat)±0.016(syst),Sf=0.691±0.029(stat)±0.014(syst).
