Factorization and heavy-quark symmetry in hadronic B -meson decays

We discuss within the context of heavy-quark symmetry a program for performing model-independent tests of the factorization scenario proposed by Dugan and Grinstein for hadronic B-meson decays. Preliminary, model-dependent results for decays to a D or D* and one, two, or three pions are presented which indicate that the predictions of factorization are consistent with the present experimental situation. Our results suggest that such decays may not only provide a precision testing ground for factorization, but also an opportunity to study the properties of excited D mesons and to measure many of the universal form factors of heavy-quark symmetry (including ones not otherwise readily accessible).
