Nonleptonic two-body B-decays including axial-vector mesons in the final state

Understand

We present a systematic study of exclusive charmless nonleptonic two-body B decays including axial-vector mesons in the final state.

• We calculate branching ratios of B\to PA, VA and AA decays, where A, V and P denote an axial-vector, a vector and a pseudoscalar meson, respectively.
• We assume naive factorization hypothesis and use the improved version of the nonrelativistic ISGW quark model for form factors in B\to A transitions.
• We include contributions that arise from the effective \Delta B=1 weak Hamiltonian H_{eff}.
