Measurement of the mass difference and relative production rate of the ${\Omega }_b^{-}$ and ${\Xi }_b^{-}$ baryons

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1050

The mass difference between the ${\Omega }_b^{-}$ and ${\Xi }_b^{-}$ baryons is measured using proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosi…
