### Abstract

We predict the branching ratios and (Formula presented) asymmetries of the (Formula presented) decays using the perturbative QCD factorization theorem, in which tree, penguin, and annihilation contributions, including both factorizable and nonfactorizable ones, are expressed as convolutions of hard six-quark amplitudes with universal meson wave functions. The unitarity angle (Formula presented) and the B and K meson wave functions extracted from experimental data of the (Formula presented) and (Formula presented) decays are employed. Since the (Formula presented) decays are sensitive to final-state interaction effects, the comparision of our predictions with future data can test the neglect of these effects in the above formalism. The (Formula presented) asymmetry in the (Formula presented) modes and the (Formula presented) branching ratios depend on annihilation and nonfactorizable amplitudes. The (Formula presented) data can also verify the evaluation of these contributions.
