QCD factorization for exclusive nonleptonic B decays

The strong-interaction dynamics of two-body hadronic B decays considerably simplifies in the heavy-quark limit, where, as has recently been proposed, a QCD factorization theorem can be written for the hadronic matrix elements. Here we summarize briefly the status of this approach and discuss some applications to B to pi pi and B to pi K decays. (11 refs).
