Determination of the Weak Phase γ from Rate Measurements in B ± → πK , ππ Decays
نویسندگان
چکیده
A method is described which, under the assumption of SU(3) symmetry, allows one to determine the angle γ = Arg(V ∗ ub) of the unitarity triangle from timeindependent measurements of the branching ratios for the rare two-body decays B+ → π0K+ and B → π0K−, as well as of the CP-averaged branching ratios for the decays B → π±K0 and B → π±π0, all of which are of order 10−5. The effects of electroweak penguin operators are included in a model-independent way, and SU(3)-breaking corrections are accounted for in the factorization approximation.

Determination of the weak phase γ = arg ( V ∗ ub )
Various strategies for extracting or constraining the weak phase γ with controlled theoretical uncertainties are reviewed. Measurements of the rates for the hadronic decays B± → πK provide largely model-independent information on γ. Hadronic uncertainties enter only at the level of nonfactorizable contributions to the decay amplitudes that are power-suppressed in Λ/mb and, simultaneously, viola...
متن کامل0 Weak Phase γ and Strong Phase δ from CP Averaged B → ππ and πK Decays
Assuming SU(3) symmetry for the strong phases in the four decay modes B → π−π+, π0π+, π−K+, π−K̄0 and ignoring the relative small electroweak penguin effects in those decays, the weak phase γ and the strong phase δ can be determined in a model independent way by the CP-averaged branching ratios of the four decay modes. It appears that the current experimental data for B → ππ and πK decays prefer...

متن کاملWeak Coupling Phase from Decays of Charged B Mesons to Πk and Ππ
The theory of CP violation based on phases in weak couplings in the Cabibbo-Kobayashi-Maskawa (CKM) matrix requires the phase γ ≡ Arg V ∗ ub (in a standard convention) to be nonzero. A measurement of γ is proposed based on charged B meson decay rates to πK, πK, ππ, and the charge-conjugate states. The corresponding branching ratios are expected to be of the order of 10. Submitted to Physical Re...
متن کاملElectroweak Penguins and Two - Body B Decays
We discuss the role of electroweak penguins in B decays to two light pseudoscalar mesons. We confirm that the extraction of the weak phase α through the isospin analysis involving B → ππ decays is largely unaffected by such operators. However, the methods proposed to obtain weak and strong phases by relating B → ππ, B → πK and B → KK decays through flavor SU(3) will be invalidated if electrowea...
