Forward – Backward Asymmetry in B → X s l + l − at the NNLL Level
We report the results of a new calculation of soft-gluon corrections in B → Xsll decays. In particular, we present the first calculation of bremsstrahlung and corresponding virtual terms to the lepton forward–backward asymmetry, which allows us to systematically include all contributions to this observable beyond the lowest non-trivial order. The new terms are important, for instance the positi...
متن کاملQCD Corrections to the Decay B → X s l + l −
We briefly discuss the status of the NNLL QCD calculations in the inclusive rare B decay B → Xsll. Two important ingredients, the two-loop matrix elements of the four quark operator O2 and the bremsstrahlung contributions, were quite recently finalised. The new contributions significantly improve the sensitivity of the inclusive decay B → Xsll decay in testing extensions of the standard model i...
متن کامل2 00 5 Exclusive B → ρ l + l − decay and Polarized lepton pair forward – backward asymmetries
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...
متن کاملEUROPEAN ORGANIZATION FOR PARTICLE PHYSICS CERN-EP/98{32 February 26, 1998 QCD corrections to the forward-backward asymmetries of c and b quarks at the Z pole
Measurements of the forward-backward production asymmetry of heavy quarks in Z decays provide a precise determination of sin lept W;e . The asymmetries are sensitive to QCD e ects, in particular hard gluon radiation. In this paper QCD corrections for A b FB and A c c FB are discussed. The interplay between the experimental techniques used to measure the asymmetries and the QCD e ects is investi...
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.
