AB Using a data sample of ppcollisions corresponding to an integrated luminosity of 3fb−1, the Ξ−band Ω−bbaryons are reconstructed in the Ξ−b→J/ψΞ−and Ω−b→J/ψΩ−decay modes and their lifetimes measured to beτ Ξ−b = 1.55+0.10−0.09 (stat)±0.03 (syst) ps,τ Ω−b = 1.54+0.26−0.21 (stat)± 0.05 (syst) ps.These are the most precise determinations to date. Both measurements are in good agreement with previous experimental results and with theoretical predictions
