Neutral current B-decay anomalies

Abstract

We discuss the implications of $b\to s{\ell }^{+}{\ell }^{-}$ 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 $B_s\to \varphi {\mu }^{+}{\mu }^{-}$ branching ratios and angular observables, the recent CMS measurement of the branching ratio of $B_s\to {\mu }^{+}{\mu }^{-}$, and the LHCb measured lepton flavour universality violating ratios $R_{K_S^0}$ and $R_{K^{\ast +}}$. 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.
