Measurement of the masses of the $\Xi_b^{-}$ and $\Omega_b^{-}$
Preliminary measurements of the $\Xi_b^{-}$ and $\Omega_b^{-}$ masses are described. The decays of these bottom baryons with strangeness $\Xi_b^{-}\rightarrow J/\psi \Xi^{-}$ and $\Omega_b^{-} \rightarrow J/\psi \Omega^{-}$ are fully reconstructed. Using 0.62 fb$^{-1}$ of data collected with the...
