Neutral current B-decay anomalies

We discuss the implications of $b \rightarrow s \ell ^+\ell ^-$ measurements and their deviations with respect to the Standard Model predictions in a model-independent framework.

Sumario:We discuss the implications of $b \rightarrow s \ell ^+\ell ^-$ 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 $B_s \rightarrow \phi \mu ^+\mu ^-$ branching ratios and angular observables, the recent CMS measurement of the branching ratio of $B_s\rightarrow \mu ^+ \mu ^-$, 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.
