Query: New ways to explore factorization in b decays   We propose to study factorization breaking effects in exclusive b decays
where they are strongly enhanced over the factorizing contributions. This can
be done by selecting final-state mesons with a small decay constant or with
spin greater than one. We find a variety of decay modes which could help
understand the dynamical origin of factorization and the mechanisms responsible
for its breaking.
