Abstract

The BABAR detector, which operates at the SLAC PEPII asymmetric e+e- collider at energies near the Y(4S) resonance has collected about 23M B-anti-B pairs in year 2000. Based on this data sample, we present the first study of sin(2b), with samples of B⁰ --> J/psi K0S, B⁰ --> psi(2S) K0S and B⁰ --> J/psi K0L decays. The measured value is 0.34+-0.20+-0.05. In addition, we present preliminary measurements of charged and neutral B meson lifetimes and B⁰-anti-B⁰ oscillation frequency.
