Nonfactorization and Final State Interactions in (B, B_s) --> ψP and ψV Decays

Abstract

Available experimental data on decay rates for B --> ψK, and decay rates and transversity amplitudes for B --> ψK^* are used to investigate nonfactorization contributions in these decays using five different theoretical models for the formfactors. Using the knowledge on nonfactorization so gained, we study the processes B_s --> ψ(η, η'), B_s --> ψϕand B --> ψ(2S) K^*. We find that present experimental data for the last two processes are consistent with the predictions of most of the models considered.
