Recent measurements of observables involving the flavour changing neutral current transition 𝑏→𝑠𝜇+𝜇− have shown an interesting pattern of tensions with respect to the predictions of the Standard Model (SM). However, the interpretation of these results is limited by our present understanding of the hadronic uncertainties affecting these predictions. Given the lepton-flavour-universal nature of the SM, observables such as 𝑅𝐾=𝐵𝑅(𝐵+→𝐾+𝜇+𝜇−)/𝐵𝑅(𝐵+→𝐾+𝑒+𝑒−), so-called Lepton Flavour Universality ratios, profit from large cancellation of the theory uncertainties and provide a very sensitive probe for physics beyond the SM. The latest measurement of the ratio 𝑅𝐾 performed by the LHCb collaboration, using the full dataset collected during Run 1 and Run2 of the LHC, will be presented.
