Abstract

This review presents recent results on key measurements of rare B and τ decays performed at the LHC and the TeVatron. Its main focus lies on recent measurements of the decay B_(s)⁰ → µ⁺µ⁻ at the two colliders and of angular observables for the decay B⁰ → K^*0µ⁺µ⁻ at the LHC experiments ATLAS, CMS and LHCb. Furthermore, the branching fraction measurement at low dilepton masses in the channel B⁰ → K^*0e⁺e⁻ from LHCb and results on the decay B^± → π^±µ⁺µ⁻ as well as on lepton-flavour- and baryon-number-violating rare decays of τ leptons are discussed.
