Abstract

We discuss the implications of b → sℓ⁺ℓ⁻ measurements and their deviations with respect to the Standard Model predictions in a model-independent framework. We highlight in particular the impact of the recent updated measurements including the updated B_s → ϕµ⁺µ⁻ branching ratios and angular observables, the recent CMS measurement of the branching ratio of B_s → µ⁺µ⁻, and the LHCb measured lepton flavour universality violating ratios $R_{K_S^0}$ and R_K^∗+. In addition, we check the compatibility of the new physics effect for the theoretically clean observables with the rest of the neutral B decays observables.
