Nonleptonic B decays to axial-vector mesons and factorization

We present an analysis of two-body B decays with a pseudoscalar (P) and an axial-vector meson (A) in the final state using factorization. We employ as inputs a limited number of experimental data, i.e. results for the B -> K-1 gamma, and B -> K-*gamma radiative decays and the branching ratios for B ->pi rho, pi K-*, K rho, K pi nonleptonic decays. In this way we are able to compare our predictions with recent data from the Belle and BABAR collaborations on B -> a(1)pi and make predictions on several other B -> PA decay channels, which might be used as a guide for experimental researches and as tests of factorization.
