Rare Beauty and Charm Decays

There are two main ways of looking for new physics, direct searches and precision measurements. The latter are sensitive to a broader spectrum of models; they also can be sensitive to higher energy scales than what can be reached through direct searches. We will provide an update of several precision measurements carried out by the LHCb collaboration. In particular, we will show the measurement of Rφπ⁽ˢ⁾, the search for Bc⁺ → π⁺μ⁺μ⁻ and Bₛ→μ⁺μ⁻γ and an amplitude analysis of the Λb⁰→ pK⁻γ decay.
