Recent measurements of the branching fractions and helicity amplitudes of the decays B –→ D ⋆ 0 ρ – and by the CLEO collaboration are presented. The fraction of longitudinal polarization in the decay is found to be consistent with the factorization hypothesis, although the helicity amplitudes show evidence for nonzero final-state interaction phases.
