At the beginning of RunII of the Tevatron and after more than 30 years of the discovery of the b quark at Fermilab, the lack of statistics had restricted our knowledge on b-baryons to the observation of the lightest b-baryon, the {lambda}{sub b}, and to its lifetime measured in decays which did not allow a fully reconstruction of this particle. I present results of the search for b-baryons in the DO experiment. As part of this program, a precise measurement of the {lambda}{sub b} lifetime was performed, and the discovery of the {xi}{sub b}{sup -} resulted from an analysis of 1.3 fb{sup -1} of data collected with the D0 detector during 2002-2006.
