Rare $B$ decays at CMS

Abstract

The Flavor Changing Neutral Current mediated decays $B\to {\mu }^{+}{\mu }^{-}$ and $B^0\to K^{\ast 0}{\mu }^{+}{\mu }^{-}$ provide high sensitivity to new physics contributions. Sensitive observables include the branching fraction, the muon forward-backward asymmetry, the fraction of $K^{\ast 0}$ longitudinal polarisation and the differential branching fraction. We report herein the recent results from CMS on these decay modes.
