Factorization vs. Flavor SU(3) in Charmless B Decays

Abstract

Two types of predictions for charmless B decays are compared. One involves estimates based on factorization and models for form factors, while the other involves the use of flavor SU(3), sometimes with assumptions about the smallness of certain amplitudes. After a comparison of some factorization predictions with recent data, specific decays of $B$ mesons to two charmless mesons are discussed.
