Towards a Theory of Hadronic B Decays
Matthias Neubert
Abstract
We review recent advances in the theory of strong-interaction effects and final-state interactions in hadronic weak decays of heavy mesons. In the heavy-quark limit, the amplitudes for most nonleptonic, two-body B decays can be calculated from first principles and expressed in terms of semileptonic form factors and light-cone distribution amplitudes. We discuss the features of this novel QCD factorization and illustrate its phenomenological implications.
