Non Leptonic Heavy Hadron Decays and Local Duality
A. Deandrea, N. Di Bartolomeo, R. Gatto, G. Nardulli
Abstract
We discuss local duality for weak non leptonic B and Lambdab decays in the mb -> infinity limit under the hypothesis of factorization and in the Shifman-Voloshin limit. We show that, under these hypotheses, local duality holds for the first two terms in the 1/mb expansion and at the order alphas in the perturbative expansion. The possible relevance of these results for the operator product expansion evaluation of the b-hadron lifetimes is discussed.
