NNLO corrections to inclusive semileptonic B decays in the shape-function region
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, w...
