Abstract

We present an analysis of two-body B decays with a pseudoscalar (P) and an axial-vector meson (A) in the final state using naive factorization. We employ as inputs a limited number of experimental data, i.e. results for the B -> K1 gamma and B -> K* gamma radiative decays and the branching ratios for B -> pion+rho, pion+K*, K+rho, K+pion non leptonic decays. In this way we are able to make predictions on several B -> P A decays that might be used as a guide for experimental researches of these decays and as tests of factorization.

Comments

Some entries in Tables V and VI modified due to new data for B->K rho decays. One reference and a comment on K1b weak coupling added. Two predictions for the channels with a kaon and a positively charged axial vector presented
