We report the observation of new bottom baryon states.
The most recent result is the observation of the baryon Xi-_b through
the decay Xi-_b --> J/psi Xi_b. The significance of the signal
corresponds to 7.7 sigma and the Xi_b mass is measured to be 5792.9 +/-
2.5(stat.) +/- 1.7(syst.) MeV/c2. In addition we observe four resonances
in the Lambda0(b) pi++/- spectra, consistent with the bottom baryons
Sigma(*)+/-_b. All observations are in agreement with theoretical
expectations.
