Test of lepton flavour universality with $B^{0} \to K^{* 0} ℓ^{+} ℓ^{-}$ decays at large dilepton invariant mass

LHCb collaboration, R. Aaij, M. Abdelfatah +1115

Muon-electron universality is tested in $B^{0} \to K^{* 0} ℓ^{+} ℓ^{-}$ decays, in the dilepton-invariant-mass region above the $I ¨ (2 S)$ resonance. The analysis uses beauty mesons…
