ISOSPIN VIOLATION IN HADRONIC B-DECAYS a
نویسنده
چکیده
I present two disparate examples of isospin violation in hadronic B-decays. In the first, the presence of ρ 0-ω mixing in the decay B ∓ → ρ ∓ ρ 0 (ω) → ρ ∓ π + π − permits the extraction of sgn(sin α), where α is the usual angle of the unitarity triangle, with minimal hadronic uncertainty. In the second, the presence of π 0-η, η ′ mixing can obscure the extraction of sin 2α from an isospin analysis in B → ππ decays.

Isospin Violation in B! Decays
An isospin analysis of B ! decays yields sin 2 , where is the usual CKM angle arg[ VtdV tb=(VudV ub)] without hadronic uncertainty if isospin is a perfect symmetry. Yet isospin symmetry is broken not only by electroweak e ects but also by the u and d quark mass di erence | the latter drives 0 ; 0 mixing and converts the isospin-perfect triangle relation between the B ! amplitudes to a quadrilat...
متن کاملIsospin Amplitudes and CP violation in ( B →
We present a simple isospin invariant parametrization for (B → Kπ) decay amplitudes which consistently includes CP violation and (quasi-elastic) hadronic final state interactions. We find that the observed (B → Kπ) decays do not lead to a significant bound on the angle γ of the unitarity triangle. On the other hand, we claim that a sizeable CP violation asymmetry in (B± → Kπ±) rates is by no me...
متن کاملTrojan Penguins and Isospin Violation in Hadronic B Decays
Some rare hadronic decays of B mesons, such as B → πK, are sensitive to isospin-violating contributions from physics beyond the Standard Model. Although commonly referred to as electroweak penguins, such contributions can often arise through tree-level exchanges of heavy particles, or through strong-interaction loop diagrams. The Wilson coefficients of the corresponding electroweak penguin oper...
متن کاملTheory of hadronic B decays
The hadronic decays of B mesons provide a unique source of information about the flavor structure of the Standard Model. Due to the peculiar hierarchy structure of the CKM matrix, CP violation is an order unity effect in B decays. After several years of data taking from the B factories BABAR and BELLE, we are now in a position to perform precision tests of the CKM mechanism for CP violation. It...
متن کاملRho - Omega Mixing and Direct CP Violation in Hadronic B - Decays S . Gardner
We study direct CP violation in hadronic B-decays in the ρ 0-ω interference region, and focus specifically on the rate asymmetry in B ± → ρ ± ρ 0 (ω) → ρ ± π + π −. In this channel, the strong phase is dominated by isospin violation, so that it can be essentially determined by e + e − → π + π − data in the ρ 0-ω interference region. We find that the asymmetry in the ρ ± π + π − channel is of or...
