Measurement of B Baryon Properties at CDF

الأصل · EN

We report on mass and mean life measurements of several ground state b-baryons, using 9.6 fb⁻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 Λb, Ξb-, Ξb⁰, and Ωb-. The first evidence for the process Ωb- → Ωc⁰ π- is also shown. The results supersede our previous measurements of these quantities.
