Measurement of the branching fraction ratio $R_{K}$ at large dilepton invariant mass

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1138

A test of lepton universality between muons and electrons is performed using $B^{+} \to K^{+} ℓ^{+} ℓ^{-}$ decays (where $ℓ$ = $e$ , $μ$ ), in the dilepton invariant-mass-squared regio…

Observation of the decay $B_{s}^{0} \to K^{0} p p ˉ$ and measurement of the $B_{(s)}^{0} \to K^{0} p p ˉ$ branching fractions

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1131

A study of the charmless baryonic decays $B_{(s)}^{0} \to K^{0} p p ˉ$ is presented, where $B_{(s)}^{0}$ denotes either a $B^{0}$ or a $B_{s}^{0}$ meson. The analysis is based on proton-pr…
