Abstract

We investigate the possibility of testing the factorization hypothesis in nonleptonic exclusive decays of the B meson. In particular, we consider the nonfactorizable B̄⁰→D^(*)+D_s^(*)- modes and B̄⁰→D^(*)+(π^-, ρ^-) known as well-factorizable modes. By taking the ratios Β(B̄⁰→D^(*)+D_s^(*)-)/Β[B̄⁰→D ^(*)+(π^-,ρ^-)], we find that under the present theoretical and experimental uncertainties there is no evidence for the breakdown of the factorization description for heavy-heavy decays of the B meson.
