Nonleptonic charmless B decays: factorization vs perturbative QCD

High Energy Physics - Phenomenology 2009-08-25 v1

Abstract

We compare the factorization approach, the perturbative QCD approach and the Beneke-Buchalla-Neubert-Sachrajda approach to nonleptonic charmless BB meson decays. We discuss their treatments of factorizable, nonfactorizable, and annihilation contributions, infrared-cutoff and scale dependences, and strong phases. It is proposed that measurement of CP asymmetries in two-body BB meson decays provides an appropriate test of the these approaches.
