QCD factorization for $B\to\pi K$ decays

高能物理 - 唯象学 2007-05-23 v1

摘要

We examine some consequences of the QCD factorization approach to non-leptonic B decays into πK\pi K and ππ\pi \pi 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.
