Abstract

Rare decays of beauty and charm hadrons provide an effective method of testing the Standard Model and probing possible new physics scenarios. The LHCb experiment has published a variety of interesting results in this field, some of which are presented here. In particular the measurements of the branching fractions of B_(s)⁰ → μ⁺μ⁻ which, in combination with CMS, resulted in the first observation of the B_s⁰ → μ⁺μ⁻ decay. Other topics include searches for the rare decay D⁰ → μ⁺μ⁻, the lepton flavour violating decays B_(s)⁰ → e^±μ^∓, and the observation of the ψ(4160) resonance in the region of low recoil in B⁺ → K⁺μ⁺μ⁻ decay. New results on the angular analysis of the decay B⁰ → K*⁰μ⁺μ⁻ with form factor independent observables are also shown.
