Electroweak penguin anomalies*

Several LHCb measurements of ratios of $B\rightarrow K^{(*)} \mu^+\mu^-$ and angular distributions in the low dimuon mass region have shown deviations greater than two standard deviations ($\sigma$) from the Standard Model. Currently, the branching fraction for $B_s^0\rightarrow \mu^+\mu^-$ obtained by averaging LHCb, CMS and ATLAS measurements is also 2.1$\sigma$ low, supporting the other results. The current status and updated results from the LHC experiments and the B-factories on ${\cal R}(K)$, ${\cal R}(K^*)$, the dilepton angular distributions, and $B_s^0\rightarrow \mu^+\mu^-$ will be shown.
