摘要：

The strong-interaction dynamics of two-body hadronic S 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 --> pi pi and B --> piK decays. (C) 2001 Elsevier Science B.V. All rights reserved.
