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 $ψ (2 S)$ resonance. The analysis uses beauty mesons…

Precision measurement of the $Ξ_{b}^{0}$ baryon lifetime

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1176

A sample of $pp$ collision data, corresponding to an integrated luminosity of 5.4 fb $^{- 1}$ and collected by the LHCb experiment during LHC Run 2, is used to measure the ratio of t…
