چکیده
We present an updated measurement of time-dependent CP-violating asymmetries in neutral B decays with the BABAR detector at the PEP-II asymmetric B Factory at SLAC. This result uses an additional sample of Upsilon(4S) decays collected in 2001, bringing the data available to 32 x 10(6) BB macro pairs. We select events in which one neutral B meson is fully reconstructed in a final state containing charmonium and the flavor of the other neutral B meson is determined from its decay products. The amplitude of the CP-violating asymmetry, which in the standard model is proportional to sin2 beta, is derived from the decay time distributions in such events. The result sin2 beta = 0.59+/-0.14(stat)+/-0.05(syst) establishes CP violation in the B(0) meson system. We also determine absolute value of lambda = 0.93+/-0.09(stat)+/-0.03(syst), consistent with no direct CP violation.

We present a measurement of the Standard Model CP violation parameter sin 2φ1 based on a 29.1 fb −1 data sample collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e− collider. One neutral B meson is fully reconstructed as a J/ψKS , ψ(2S)KS , χc1KS , ηcKS , J/ψKL or J/ψK ∗0 decay and the flavor of the accompanying B meson is identified from its decay product...
متن کاملNew Time Distributions of D-D̄ or B-B̄ Mixing and CP Violation
The formulae for D0-D̄0 or B0-B̄0 mixing and CP violation at the τ -charm or Bmeson factories are derived, for the case that only the decay-time distribution of one D or B meson is to be measured. In particular, we point out a new possibility to determine the D0-D̄0 mixing rate in semileptonic D decays at the Ψ(4.14) resonance; and show that both direct and indirect CP asymmetries can be measured ...
متن کامل{ 1{ B 0 {b 0 Mixing and Cp Violation in B Decay
The neutral B meson system is like the neutral kaon system, in that two CP-conjugate states exist. For early work on CP violation in the B system see Ref. 1. The mass eigenstates are not CP eigenstates, but are mixtures of the two CP-conjugate quark states, the mixing being due to box diagrams, shown in Figure 1. The two mass eigenstates can be written
متن کامل– 1 – PRODUCTION AND DECAY OF b - FLAVORED HADRONS
The b quark belongs to the third generation of quarks and is the weak–doublet partner of the t quark. The existence of the third–generation quark doublet was proposed in 1973 by Kobayashi and Maskawa [1] in their model of the quark mixing matrix (“CKM” matrix), and confirmed four years later by the first observation of a bb meson [2]. In the KM model, CP violation is explained within the Standa...
متن کاملPossible Signals of D 0 - D̄ 0 Mixing and CP Violation
In view of the discovery potential associated with the future experiments of high-luminosity xed target facilities, B-meson factories and-charm factories, we highlight some typical signals of D 0-D 0 mixing and CP violation which are likely to show up in neutral D-meson decays to the semileptonic nal states, the hadronic CP eigenstates, the hadronic non-CP eigenstates and the CP-forbidden state...
متن کاملCP-violation in b → s Penguin Decays at BaBar
We present the new and updated BABAR measurements of CP -violation studies for many b → s penguin decay modes. We report the first observation of mixing-induced CP -violation in B → η ′ K with a significance (including systematic uncertainties) of 5.5σ. We also present the first observation of the decay B → ρK. Using the time-dependent Dalitz plot analysis of B → KKK decay, the CP -parameters A...
