NNLO corrections to inclusive semileptonic B decays in the shape-function region
- Abstract:
-
We compute 2-loop QCD corrections to the hard coefficient functions which arise in the factorization formula for B → X u ℓ ν decays in the shape-function region. Our calculation provides the last missing piece required for a NNLO analysis of inclusive semileptonic B decays, which may significantly reduce the theoretical uncertainty in the extraction of the CKM matrix element | V u b |. Among the technical aspects, we find that the 2-loop hard co...
