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) ×106Υ(4S)→BB̄ decays collected with the BABAR detector at the PEP-II B factory. We determine sin 2β=0.714±0.032(stat) ±0.018(syst) and |λ|=0.952±0.022(stat)±0.017(syst). © 2007 The American Physical Society.
