Abstract
Available experimental data on decay rates for B --> \psi K, and decay rates and transversity amplitudes for B --> \psi K^* 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 --> \psi (\eta, \eta'), B_s --> \psi \phi and B --> \psi(2S) K^*. We find that present experimental data for the last two processes are consistent with the predictions of most of the models considered.
