Book excerpt: We show that, in the heavy quark limit, the hadronic matrix elements that enter B meson decays into two light mesons can be computed from first principles, including ''non-factorizable'' strong interaction corrections, and expressed in terms of form factors and meson light-cone distribution amplitudes. The conventional factorization result follows in the limit when both power corrections in 1/m{sub b} and radiative corrections in?{sub s} are neglected. We compute the order-?{sub s} corrections to the decays B{sub d} →??−, B{sub d} →?°?° and B+ →?+?° in the heavy quark limit and briefly discuss the phenomenological implications for the branching ratios, strong phases and CP violation.
