The measurements use a data sample of ( 383 ± 4 ) × 10 6   Υ ( 4 S ) → B ¯¯¯ B decays collected with the BABAR detector at the PEP-II B factory. We determine sin  2 β = 0.714 ± 0.032 ( stat ) ± 0.018 ( syst ) and | λ | = 0.952 ± 0.022 ( stat ) ± 0.017 ( syst ) .7 p.application/pdfeng(c) American Physical Society, 2007Física de partículesExperimentsParticle physicsExperimentsinfo:eu-repo/semantics/article5582012019-09-16info:eu-repo/semantics/openAccess
