Abstract

We present results on time-dependent CP asymmetries in neutral B decays to several CP eigenstates. The measurements use a data sample of about 227 * 10^6 Y(4S) BB decays collected by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. The amplitude of the CPasymmetry, sin 2beta in the standard model, is derived from decay-time distributions from events in which one neutral B meson.
