QCD factorization for BπK decays
M. Beneke, G. Buchalla, M. Neubert, C. T. Sachrajda
Abstract
We 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.
