Title: Heavy flavor baryon states at the Tevatron

Abstract

Precision measurements of the masses and widths of the bottom baryon resonances Σ{sub b} and Σ* and charm baryons Λ{sub c}(2595), Λ{sub c}(2625), Σ{sub c}(2455), and Σ{sub c}(2520) are reported. A new measurement of Λ{sub b} production is described. The studies include the first measurement of the widths and isospin mass splittings of the members of the Σ{sub b} family. The charm baryons are examined through their strong decays to the Λ{sub c} ground state, and measurements of their mass differences relative to the ground state, and corresponding decay widths, are reported. The data were collected by the CDF and D0 detectors for 1.96 TeV proton-antiproton collisions during Run II at the Fermilab Tevatron.
