Abstract

We report on mass and mean life measurements of several ground state bb-baryons, using 9.6 fb1\textrm{fb}^{-1} of data from ppˉp\bar p collisions at s=1.96\sqrt{s}=1.96 TeV, and recorded with the Collider Detector at Fermilab. Data collected with triggers designed to collect events with J/ψμ+μJ/\psi \rightarrow \mu^+ \, \mu^- candidates and events with hadrons displaced from the beamline are used to measure the masses and lifetimes of Λb,Ξb,Ξb0\Lambda_b, \Xi_b^-, \Xi_b^0, and Ωb\Omega_b^-. The first evidence for the process ΩbΩc0π\Omega_b^- \rightarrow \Omega_c^0 \, \pi^- is also shown. The results supersede our previous measurements of these quantities.
