Physics with $B\to {\eta }^{\prime }$ and $B\to J/\psi$

Abstract

In this talk I discuss two topics related to B decays. I will first discuss the Standard Model prediction for $B\to {\eta }^{\prime }{X}_s$, and then discuss how to use experimental information from $B\to J/\psi K^{\ast }$ to test CP violation beyond the SM.
