QCD improved exclusive rare B-decays at the heavy b-quark limit
Description
The renormalization effects from the b-quark scale down to the non-perturbative QCD regime are studied for rare B-decays at the heavy b-quark limit. Phenomenological consequences of these effects are investigated. We find that the anomalous scaling behaviour plays a positive role in making non-perturbative model calculations consistent with recent CLEO measurements of B → K*γ. (author). 21 refs, 3 tabs
