摘要：We apply the QCD factorization approach to exclusive, radiative B meson
decays in the region of small invariant photon mass. We calculate factorizable and nonfactorizable
corrections to leading order in the heavy quark mass expansion and nextto-
leading order in the strong coupling constant. Phenomenological consequences for the
B ! K decay rate and the B ! K`+`− forward-backward asymmetry are discussed.
