Abstract
We propose to study factorization breaking effects in exclusive b decays wh ere they are strongly enhanced over the factorizing contributions. This can be done by selecting final-state mesons with a small decay constant or wit h spin greater than one. We find a variety of decay modes which could help understand the dynamical origin of factorization and the mechanisms respons ible for its breaking.
