We compute O(αs) and O (αsn β0n-1) (BLM) corrections to the five structure functions relevant for b → q ℓ ν̄ decays and apply the results to the moments of a few distributions of phenomenological importance.

Abstract
We compute O(αs) and O (αsn β0n-1) (BLM) corrections to the five structure functions relevant for b → q ℓ ν̄ decays and apply the results to the moments of a few distributions of phenomenological importance. We present compact analytic one-loop formulae for the structure functions, with proper subtraction of the soft divergence. © 2005 Elsevier B.V. All rights reserved.
