Abstract

Status of nonfactorizable effects in hadronic charmless B decays is reviewed. Implications of new CLEO measurements on B⁰→π⁺π^- and B→η' K are discussed. Nonfactorizable effects due to color ocet 4-quark operators are calculated using renormalization group improved QCD sum rules. The resultant B-meson lifetime ratio τ(B^-)/τ(B_d) agrees with experiment.
