title = "Measurement of the CP-violation parameter sin(2β) in B0 d/B-0 d → J/ψK0 S decays",
abstract = "We present a measurement of the time-dependent asymmetry in the rate for B-0 d versus B0 d decays to J/ψK0 S. A nonzero asymmetry would be an indication of CP violation, and within the standard model this may be used to measure the CP-violation parameter sin(2β)2. A total of 198 ± 17 B0 d/B¯0 d decays were observed in 99¯ collisions at √s = 1.8 TeV by the CDF detector at the Fermilab Tevatron. B0 d and B¯0 d are distinguished by a technique based on charge correlations from hadronization of the b quark. Our analysis results in sin(2β) = 1.8 ± 1.1(stat) ± 0.3(syst).",
