2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/39795We examine some consequences of the QCD factorization approach to non-leptonic B decays into $πK$ and $ππ$ final states, including a set of enhanced power corrections. Among the robust predictions of the approach we find small strong-interaction phases (with one notable exception) and a pattern of CP-averaged branching fractions, which in some cases differ significantly from the current central values reported by the CLEO Collaboration.4 pages, LaTeX, Contribution to ICHEP2000, July 27 - August 2, Osaka, Japan, to appear in the ProceedingsHigh Energy Physics - Phenomenologytext
