New Strategies to Extract CKM Phases from Non-Leptonic B Decays
نویسنده
چکیده
Several new strategies to extract CKM phases, including a determination of γ from Bs(d) → J/ψKS decays and a general approach, which makes use of the angular distributions of certain Bd,s modes, such as Bd → J/ψ ρ 0 and Bs → J/ψ φ, are discussed. Special emphasis is put on a simultaneous determination of β and γ with the help of the decays Bd → π π and Bs → K K, which relies only on the U -spin flavour symmetry of strong interactions and is not affected by any penguin or final-state-interaction effects. Talk given at the International Europhysics Conference on High Energy Physics – EPS-HEP ’99, Tampere, Finland, 15–21 July 1999 To appear in the Proceedings CERN-TH/99-243 August 1999

CP Violation and the Role of Electroweak Penguins in Non-leptonic B Decays
The phenomenon of CP violation in the B system and strategies for extracting CKM phases are reviewed. We focus both on general aspects and on some recent developments including CP-violating asymmetries in Bd decays, the Bs system in light of a possible width difference ∆Γs, charged B decays, and SU(3) relations among certain transition amplitudes. In order to describe the relevant non-leptonic ...
متن کاملCKM angles from non-leptonic B decays using SU(3) flavour symmetry
We discuss the determination of the CKM angles γ and α using recent data from non-leptonic B decays together with flavour symmetries. Penguin effects are controlled by means of the CP-averaged branching ratio Bd → π K. The information from ACP (Bd → J/ΨKS) (two solutions for φd), Rb and γ allow us to determine β, even in presence of New Physics not affecting ∆B = 1 amplitudes. In this context w...
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 کاملDetermination of γ and α from non-leptonic B decays with SU(3) flavour symmetry
In this talk we try to answer the question of how far we can get to determine the CKM angles using as inputs experimental data and symmetries, and trying to minimize as much as possible hadronic uncertainties from QCD. Since data seems to indicate that penguins play a fundamental role, any method should include their contribution[ 2, 3, 4]. We shall discuss, here, the method we have used in[ 2,...
متن کاملCkm Matrix from Non-leptonic B-decays
We analyze the impact of the forthcoming CP-violating observables in the Bs → K + K − system, combined with the precise measurement of sin 2β , in the extraction of the CKM matrix. Computing the penguin parameters (r, θ) within QCD factorization yields a precise determination of (¯ ρ, ¯ η), reflected by a weak dependence on θ, which is shown to be a second order effect. Using the SU (3)-flavour...
