Complete gluon bremsstrahlung corrections to the process b → s l + l − ∗

چکیده
In a recent paper [1], we presented the calculation of the O(α s) virtual corrections to b → s ℓ + ℓ − and of those bremsstrahlung terms which are needed to cancel the infrared divergences. In the present paper we work out the remaining O(α s) bremsstrahlung corrections to b → s ℓ + ℓ − , which do not suffer from infrared and collinear singularities. These new contributions turn out to be small numerically. In addition, we also investigate the impact of the definition of m c on the numerical results.

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...

We calculate the O(s) gluon Bremsstrahlung corrections to the inclusive decay b ! ss, involving the full operator basis ^ O 1 { ^ O 8. Connrming and extending earlier calculations of Ali and Greub, we give formulas for the total decay width as well as the perturbative photon spectrum, regarding the former as a necessary part of the forthcoming complete NLO analysis. We explore in detail the ren...

We present the results of the O(αs) two-loop virtual corrections to the differential decay width dΓ(B → Xsll)/dŝ, where ŝ is the invariant mass squared of the lepton pair, normalized to m b . Those contributions from gluon bremsstrahlung which are needed to cancel infrared and collinear singularities are also included. Our calculation is restricted to the range 0.05 ≤ ŝ ≤ 0.25 where the effects...
