Electroweak Penguins and Constraints on Γ
نویسنده
چکیده
Electroweak penguin (EWP) amplitudes are studied model-independently in B meson decays to charmless final states consisting of a vector meson (V ) and a pseudoscalar meson (P ). A set of SU(3) relations is derived between EWP contributions and tree amplitudes, in the approximation of retaining only the dominant EWP operators Q9 and Q10. Two applications are described for constraining the weak phase γ, in B± → ρ±K0 and B± → ρ0K± (or B± → K∗±π0 and B± → K∗0π±), and in B → K∗±π∓ and B± → φK±. PACS numbers: 13.25.Hw, 14.40.Nd, 11.30.Er, 12.15.Ji

Electroweak 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...
متن کاملStrategies for Fixing the CKM-angle γ and Obtaining Experimental Insights into the World of Electroweak Penguins
Using the SU(3) flavour symmetry of strong interactions, we propose strategies for extracting both the CKM-angle γ and the b̄ → ūus̄ tree-level amplitude T ′. We present also an approximate approach using the branching ratios for the modes B → πK, B d → π−K+, B̄ d → π+K− and B → ππ which should be rather promising from the experimental point of view. The quantities γ and T ′ determined this way ma...
متن کاملTowards the Extraction of the CKM Angle γ
The determination of the angle γ of the unitarity triangle of the CKM matrix is regarded as a challenge for future B-physics experiments. In this context, the decays B ± → π ± K and B d → π ∓ K ± , which were observed by the CLEO collaboration last year, received a lot of interest in the literature. After a general parametrization of their decay amplitudes , strategies to constrain and determin...

Electroweak penguin operators become important when m t ≈ 174 GeV. We discuss their implications for measuring CP violating phases α, β and γ.
متن کاملControlling Rescattering Effects in Constraints on the CKM Angle γ arising from B → πK Decays
It has recently been pointed out that the observables of the decay B+ → K+K0 and its charge conjugate allow us to take into account rescattering effects in constraints on the CKM angle γ arising from B → πK and Bd → πK modes, and that they play an important role to obtain insights into final-state interactions. In this paper, the formalism needed to accomplish this task is discussed in detail. ...
