Establishing a Search for $b \rightarrow s \ell^{+} \ell^{-}$ Anomalies at the LHC

Understand

One of the fundamental predictions of the Standard Model is Lepton Flavour Universality.

• Any deviation from this prediction would indicate the existence of physics beyond the Standard Model.
• Recent LHCb measurements present a pattern of deviations from this prediction in rare B-meson decays.
• While not yet statistically significant (currently $2.2-2.6 \sigma$), these measurements show an imbalance in the ratio of B-meson decays to a pair of muons in association with a Kaon and decays to a pair of electrons in association with a Kaon.
