Using recent determinations of the non-perturbative parameters of the Operator Product Expansion we compute the normalization factor for the branching ratio of B->X_s gamma and find a few percent enhancement with respect to previous determinations.11 pages, 1 fig; minor numerical changes, text improved, matches version to appear in PLBHigh Energy Physics - Phenomenologytext
