Present Status of $b \to s \ell^+ \ell^−$ Anomalies

International audienceWe discuss the observed deviations in b→sℓ+ℓ− processes from the Standard Model predictions and present global fits for the New Physics description of these anomalies. We further investigate the stability of the global fits under different theoretical assumptions and suggest strategies and a number of observables to clear up the source of the anomalies
