Title: BaBar Explores CP Violation

Abstract

The most recent results obtained by the BABAR experiment at the PEP-II asymmetric-energy B Factory at SLAC on CP-violating asymmetries and branching fractions for neutral and charged B decays are presented here. The analysis was performed on a data sample of {approx} 88 million {Upsilon}(4S) {yields} B{bar B} decays collected between 1999 and 2002. Using b {yields} c{bar c}s decays, we measure sin2{beta} = 0.741 {+-} 0.067(stat) {+-} 0.034(syst). We also present sin2{beta} measurements from, b {yields} s{bar s}s and b {yields} c{bar c}d processes. From neutral B meson decays to two-body final states of charged pions and kaons, we derive for the CP violating parameters, S{sub {pi}{pi}} = 0.02 {+-} 0.34 {+-} 0.05 [-0.54, +0.58] and C{sub {pi}{pi}} = -0.30 {+-} 0.25 {+-} 0.04 [-0.72, +0.12]. First results for B {yields} {pi}{sup +}{pi}{sup -}{pi}{sup 0} and K{sup {+-}}{pi}{sup {-+}}{pi}{sup 0} final states dominated by the {rho}{sup {+-}} resonance, are also presented.
