The CKM phase α through B → a0π
نویسندگان
چکیده
We propose the decay modes B → a0(→ ηπ)π to determine the CKM phase α. One can analyze these modes through (i) the B → a0π isospin pentagon, (ii) the time dependent Dalitz plot of B0(t) → a±0 π → ηπ+π−, and (iii) the time dependence of B0(t) → a0(→ ηπ0)π0. We show that the a0π modes have certain advantages as compared to the ρπ modes, and strongly recommend the time dependent Dalitz plot analysis in the a0π channel.

متن کاملCkm Unitarity Angles Α ( Φ 2 ) and Γ ( Φ
In the Standard Model, the origin of CP-violation lies in the charged weak interaction sector, which involves transitions amongst quarks of different flavor and charge through the emission of a virtual W . The coupling strengths of these transitions for the 3 generations of quarks form a 3×3 matrix first introduced by M. Kobayashi and T. Maskawa and known as the (CKM) matrix. The CKM matrix is ...
متن کاملMeasurements of the angle α ( φ 2 ) at B factories
into play the two elements of the CKM matrix which are non real at lowest order: Vub, involved in decays proceeding via a b to u transtion, whose phase is −γ, and Vtd, involved in B B̄ mixing, whose phase is −β. So α = π− β− γ can be measured from CP violating asymmetries in the interference between mixing and decay in charmless decays of the neutral B mesons, such as B → ππ, B → ρρ, B → πππ, an...

We reanalyze the decay Bd → π+π− without assuming dominance of QCD penguins with internal top-quark exchanges. In that case the weak phase of the b̄ → d̄ QCD penguin amplitude is not related in a simple way to the CKM angle β. Nevertheless it is still possible to extract the CKM angle α in a transparent and almost modelindependent way from the time-dependent CP-violating asymmetry of the transiti...
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...
