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) → B B decays collected with the BABAR detector at the PEP-II B factory. The time-dependent CP asymmetry parameters measured from J/ψK_S⁰, J/ψK_L⁰, ψ(2S) K_S⁰, χ_c1 K_S⁰, η_c K_S⁰, and J/ψK^*0 decays are C_f = 0.026 ± 0.020(stat) ± 0.016(syst), S_f = 0.691 ± 0.029(stat) ± 0.014(syst).
