Abstract

We report on mass and mean life measurements of several ground state b-baryons, using 9.6 \textrmfb^-1 of data from p p collisions at √(s)=1.96 TeV, and recorded with the Collider Detector at Fermilab. Data collected with triggers designed to collect events with J/ψ→ μ⁺ μ^- candidates and events with hadrons displaced from the beamline are used to measure the masses and lifetimes of Λ_b, Ξ_b^-, Ξ_b⁰, and Ω_b^-. The first evidence for the process Ω_b^- → Ω_c⁰ π^- is also shown. The results supersede our previous measurements of these quantities.
