Angular Distribution of Charming B -> V V Decays and Time Evolution Effects

Abstract

Angular distributions of a B meson decaying into two vector mesons are discussed with emphasis on time evolution effects on the complete set of amplitude bilinears. Time integrated quantities are suggested to observe substantial CP violation in decays with charm quarks in the final state particles. Relations among the nine observables at $t=0$ are found to be useful for a consistency check of experimentally extracted quantities. Numerical estimates of the nine observables are made using form factor models and the assumption of the factorization hypothesis. Branching ratio asymmetries for B_u^+ -> D^{*+} \bar D^{*0} and B_d -> D^{*+} D^{*-} can be as large as -3% and -4%, respectively.
