Measurement of the [xi]-b and [omega]-b baryon lifetimes

Using a data sample of pp collisions corresponding to an integrated luminosity of 3 fb−1, the Ξb− and Ωb− baryons are reconstructed in the Ξb−→J/ψΞ− and Ωb−→J/ψΩ− decay modes and their lifetimes measured to beτ(Ξb−)=1.55−0.09+0.10 (stat)±0.03 (syst) ps,τ(Ωb−)=1.54−0.21+0.26 (stat)±0.05 (syst) ps.

Description
Summary:Using a data sample of pp collisions corresponding to an integrated luminosity of 3 fb−1, the Ξb− and Ωb− baryons are reconstructed in the Ξb−→J/ψΞ− and Ωb−→J/ψΩ− decay modes and their lifetimes measured to beτ(Ξb−)=1.55−0.09+0.10 (stat)±0.03 (syst) ps,τ(Ωb−)=1.54−0.21+0.26 (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.
