Rare decays at LHCb

Abstract

Flavour-changing neutral-current processes, such as $b\to s{\ell }^{+}{\ell }^{-}$, are forbidden at tree level in the Standard Model and hence might receive comparatively large corrections from new particles. This document highlights recent measurements from LHCb on $b\to s{\ell }^{+}{\ell }^{-}$ and purely-leptonic decays, including tests of lepton flavour universality and searches for lepton flavour violation.
