چکیده
As a sequel to the calculation of the CP-violating asymmetry in the decay rates of b → d l + l − and ¯ b → ¯ d l + l − , we address in this paper the asymmetry in exclusive channels ¯ B → π e + e − and ¯ B → ρ e + e − , using form factors from two different models. In the invariant mass region 1 GeV < √ s < M J/ψ , the partial width asymmetry in the channel ¯ B → π is −6% (−2%), and that in the channel ¯ B → ρ, for one choice of form factors, is −5% (−2%), assuming CKM parameters η = 0.34, ρ = 0.3 (−0.3). We also calculate the forward-backward asymmetry

متن کاملFlavour-Conserving CP Phases in Supersymmetry and Implications for Exclusive B Decays
We study rare exclusive B decays based on the quark-level transition b → s(d) l+l−, where l = e or μ, in the context of supersymmetric theories with minimal flavour violation. We present analytic expressions for various mixing matrices in the presence of new CP-violating phases, and examine their impact on observables involving B and B̄ decays. An estimate is obtained for CPviolating asymmetries...
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...
متن کاملul−νl decays in the MSSM with and without R-parity violation
We study the exclusive b → ulνl (l = τ, μ, e) decays in the MSSM with and without R-parity violation. From the experimental measurements of branching ratios B(B− u → τ−ντ ), B(B− u → M lνl′) and B(B 0 d → M lνl′) (l′ = μ, e, M ′ = π, ρ), we derive new upper bounds on the relevant new physics parameters within the decays. Using the constrained new physics parameter spaces, we predict the charged...
متن کاملB Decays to D
The e + e − annihilation data recorded with the BABAR detector has been used to study B 0 decays to D (*)+ s and D * − mesons. The production fraction of inclusive D (*)+ s and the corresponding momentum spectra have been determined. Exclusive decays B 0 → D * − D (*)+ s have been identified with a partial reconstruction technique and their branching ratios have been measured. Fully reconstruct...
