Abstract
The b → sl+l− transitions are flavour-changing neutral currents, where new physics can enter in competing loop diagrams with respect to the Standard Model contributions. In these decays several observables sensitive to new physics and where theoretical uncertainties are under control can be built. Particularly interesting are the angular asymmetries in the decay Bd → K ∗ μ+μ− and the measurement of the branching ratio of the decays Bs,d → μ+μ−. Recent measurements of these observables and implications for the search of physics beyond the Standard Model will be discussed. Measurements of the isospin asymmetry in the decays B → K(∗)l+l− and the measurement of the branching ratio of the decay B+ → π+μ+μ− will also be discussed.
