Test of lepton universality using B⁺→K⁺ℓ⁺ℓ⁻ decays
Several hints of potential $B$ physics anomalies have been observed in recent years. Some of the observables, such as $R_{K}$, the ratio of branching fractions of $B^{+}\to K^{+}\mu^{+}\mu^{-}$ to that of $B^{+}\to K^{+}e^{+}e^{-}$, have exhibited deviations from the standard model prediction. This...
