Theory and phenomenology of non-leptonic heavy meson decay

Alexey A Petrov, University of Massachusetts Amherst


The non-leptonic decays of heavy mesons are considered. A novel resummation technique to study the factorization approximation based on the Operator Product Expansion is introduced and employed to explore leading non-factorizable corrections to B-meson decay. Soft Final State Interactions are studied in the heavy quark limit and found to be dominated by the multiparticle intermediate states. It is shown that soft Final State Interactions do not disappear in the large $m\sb{B}$ limit thus bringing non-perturbative uncertainty to the calculations and extractions of the CKM matrix elements. Phenomenological applications of these findings are also considered.
