description | Electroweak penguin decays proceed via favour changing neutral currents, which are heavily (loop-)suppressed in the Standard Model (SM).
They therefore constitute sensitive probes for new heavy particles beyond the SM that can give significant virtual contributions.
These contributions can modify branching fractions and angular observables of rare $b\to s\ell^+\ell^-$ decays.
Recent measurements in this area have shown tensions with SM predictions, which are colloquially referred to as flavour anomalies.
These proceedings discuss the status of the anomalies in rare $b\to s\mu^+\mu^-$ decays, focusing on the latest measurements by the LHCb collaboration. |
