Measurement of sin 2β in Tree Dominated B0 Decays and Ambiguity Removal
نویسنده
چکیده
The most recent results from the B-factories on the time-dependent CP asymmetries measured in B -decays mediated by b → cc̄s quark-transitions are reviewed. The Standard Model interpretation of the results in terms of the parameter sin 2β leads to a four-fold ambiguity on the unitarity triangle β which can be reduced to a two-fold ambiguity by measuring the sign of the parameter cos 2β. The results on cos 2β obtained so far are reviewed.

متن کاملBabar: Sin(2β + Γ) Babar: Sin(2β + Γ)
The time-dependent CP asymmetries in fully reconstructed B0→D(∗)±π∓/ρ∓ decays (new preliminary result), and in partially reconstructed B0→D(∗)±π∓ decays, are measured with the BABAR detector at the PEP-II asymmetric B factory at SLAC, using 232 million Υ (4S) → BB decays. We combine the above results and, using other measurements and theoretical assumptions, we interpret them in terms of the an...
متن کاملPhenomenological methods for unitarity triangle angles
The Kobayashi-Maskawa model for CP violation [1] passed in a remarkable way its first crucial test in B decays [2] when a large CP asymmetry was measured [3, 4] in B → J/ψKS in agreement with expectations. The virtue of this gold-plated decay mode is the absence of hadronic uncertainties [5, 6] in predicting the mixing induced asymmetry in terms of a fundamental phase parameter β ≡ φ1 of the St...
متن کاملA Consistent Resolution of Possible Anomalies in B 0 → φK S and B + → η ′ K + Decays
In the framework of R-parity violating (Rp / ) supersymmetry, we try to find a consistent explanation for both recently measured CP asymmetry in B0 → φKS decay and the large branching ratio of B → ηK decay, which are inconsistent with the Standard Model (SM) prediction. We also investigate other charmless hadronic B → PP and B → V P decay modes whose experimental data favor the SM: for instance...
متن کاملCP Violation in B Decays at the Tevatron
Between 1992 to 1996, the CDF and D0 detectors each collected data samples exceeding 100 pb−1 of pp̄ collisions at √ s = 1.8 TeV at the Fermilab Tevatron. These data sets led to a large number of precision measurements of the properties of B hadrons including lifetimes, masses, neutral B meson flavor oscillations, and relative branching fractions, and to the discovery of the Bc meson. Perhaps th...
