QCD factorization in $B \to \pi K$, $\pi\pi$ decays and extraction of Wolfenstein parameters
In the heavy-quark limit, the hadronic matrix elements entering nonleptonic $B$-meson decays into two light mesons can be calculated from first principles including ``nonfactorizable'' strong-interaction corrections. The $B\to\pi K,\pi\pi$ decay amplitudes are computed including electrowea...
