2 00 5 Exclusive B → ρ l + l − decay and Polarized lepton pair forward – backward asymmetries
نویسنده
چکیده
The polarized lepton pair forward–backward asymmetries in B → ρl+l− decay using a general, model independent form of the effective Hamiltonian is studied. The general expression for nine double–polarization forward–backward asymmetries are calculated. The study of the forward–backward asymmetries of the doubly–polarized lepton pair proves to be very useful tool in looking for new physics beyond the standard model.

متن کاملPolarized forward – backward asymmetries of leptons in B s → l + l − γ decay
Polarized forward–backward asymmetries in the Bs → l+l−γ decay are calculated using the most general, model independent form of the effective Hamiltonian, including all possible forms of interactions. The dependencies of the asymmetries on new Wilson coefficients are investigated. The detectability of the asymmetries at LHC is discussed.

متن کاملDouble-Lepton Polarization Asymmetries and Polarized Forward Backward Asymmetries in The Rare b → sl+l− Decays in a Single Universal Extra Dimension Scenario
We study the double-lepton polarization asymmetries and single and double-lepton polarization forward backward asymmetries of the rare b → sl+l− mode within the Standard Model and in the Appelquist-Cheng-Dobrescu model, which is a new physics scenario with a single universal extra dimension. In particular, we examine the sensitivity of the observables to the radius R of the compactified extra-d...
متن کاملViolation in the Exclusive Decays B → π e + e − and B → ρ e + e −
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...
