Annihilation amplitudes and factorization in $B^\pm\to\phi K^{*\pm}$

Abstract. We study the decay $B^\pm\to\phi K^{*\pm}$, followed by the decay of the outgoing vector mesons into two pseudoscalars. The analysis of the angular distributions of the decay products is shown to provide useful information about the annihilation contributions and possible tests of factorization.
