Non-Factorization in $(B,B_s)\to P(V)\psi$ Decays

Abstract

Available experimental data on decay rate and polarization are used to investigate non-factorization contribution to processes of the kind $B\to K\psi$, and $B\to K^{\ast }\psi$ using five theoretical models for the formfactors. Using the knowledge on non-factorization gained from $B$ decays we study the processes $B_s\to ({\eta }^{\prime },\eta )\psi$, and $B_s\to \varphi \psi$ where experimental data are very limited.
