Measurement of branching fractions and $C P$ asymmetries in $Λ_{b}^{0} (Ξ_{b}^{0}) \to p K_{S}^{0} h^{-}$ decays

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1160

A study of $Λ_{b}^{0}$ and $Ξ_{b}^{0}$ baryon decays to the final states $p K_{S}^{0} π^{-}$ and $p K_{S}^{0} K^{-}$ is performed using $pp$ collision data collected by t…

Measurement of the Z-boson mass

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1129

The first dedicated $Z$ -boson mass measurement at the LHC with $Z \to μ^{+} μ^{-}$ decays is reported. The dataset uses proton-proton collisions at a centre-of-mass energy of $13$ TeV,…
