| dc.description.abstract | Using a data sample of pp collisions corresponding to an integrated luminosity of 3 fb−1, the Ξ−b and Ω−b baryons are reconstructed in the Ξ−b→J/ψΞ− and Ω−b→J/ψΩ− decay modes and their lifetimes measured to be τ(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. | eng |
