CP Violation and Strategies for Extracting CKM Phases
The phenomenon of CP violation and strategies for extracting the angles of the unitarity triangle are reviewed. Special emphasis is given to the B-meson system, as it plays an outstanding role to test the Standard Model description of CP violation at future experimental B-physics facilities. Both general aspects and recent developments are discussed. It is pointed out that combined branching ra...
متن کاملCP Violation in B Decays and Strategies for Extracting CKM Phases
A brief review of CP violation in the B-meson system and of strategies to determine the angles α, β and γ of the unitarity triangle of the CKM matrix is given. Both general aspects and some recent developments are discussed, including a critical look at the “benchmark” modes, CP violation in penguin decays, Bs decays in the light of the width difference ∆Γs, charged B decays, and strategies to ...
متن کاملExtracting CKM Phases and Bs–Bs Mixing Parameters from Angular Distributions of Non-Leptonic B Decays
Suggestions for efficiently determining the lifetimes and mass difference of the light and heavy Bs mesons (B L s , B H s ) from Bs → J/ψφ,D∗+ s D∗− s decays are given. Using appropriate weighting functions for the angular distributions of the decay products (moment analysis), one can extract (ΓH ,ΓL,∆m)Bs . Such a moment analysis allows the determination of the relative magnitudes and phases o...
متن کاملExtracting information on CKM phases , electro - weak penguins and new physics from B →
We derive constraints for B → V V modes (V = vector meson) that allow a quantitative assessment of the contributions from electroweak penguins (EWP) and/or new physics. Interplay of direct CP with oscillation studies then leads to the extraction of the angles α and γ, using B → Kω(ρ) andB → ρω(φ) respectively, if by using our constraint equations it can be experimentally demonstrated that color...
متن کاملCKM Phases from CP Asymmetries
Measuring phases in the Cabibbo-Kobayashi-Maskawa matrix through CP asymmetries in B decays is a major goal of current and future experiments. Methods based on charge-conjugation and isospin symmetries involve very little theoretical uncertainties, while schemes based on flavor SU(3) involve uncertainties due to SU(3) breaking. Resolving these uncertainties requires further studies involving a ...
