Exclusive Charmless $B$ Decays in QCD

High Energy Physics - Phenomenology 2011-03-23 v1

Abstract

The problem of hadronic input in charmless nonleptonic B decays is discussed. QCD sum rules and their light-cone versions (LCSR) provide an important part of this input, such as the decay constant fBf_B and BπB\to \pi form factor. Employing the LCSR technique, the BππB\to \pi\pi hadronic matrix elements with emission, penguin and annihilation topologies are calculated, with no evidence for large nonfactorizable effects and/or strong phases.
