Title: CP Violation in B Decays and the BaBar Experiment

DOI:https://doi.org/10.2172/798915· OSTI ID:798915

During the first year of data taking, the 1999-2000 run, the BABAR detector at the SLAC PEP-II asymmetric collider has collected an integrated luminosity of 20.7 fb{sup -1} corresponding to 22.7 million B{bar B} pairs at the {Upsilon}(4S) resonance. Using this data, we present the measurement of sin2{beta} based on samples of B{sup 0} {yields} J/{psi} K{sub S}{sup 0}, B{sup 0} {yields} {psi}(2S) K{sub S}{sup 0} and B{sup 0} {yields} J/{psi} K{sub L}{sup 0} L decays. Our measured value is sin2{beta} = 0.34 {+-} 0.20 (stat) {+-} 0.05 (syst). In addition we report on the measurement of branching fractions for exclusive B decays to charmonium final states, measurements of charged and neutral B meson lifetimes and also the B{sup 0}{bar B}{sup 0} oscillation frequency.
