Abstract

The Tevatron experiments CDF and D0 have filled many empty spots in the spectrum of heavy baryons over the last few years. The most recent results are described in this article: The first direct observation of the Xi_b^0, improved measurements of Sigma_b properties, a new measurement of the Lambda_b -> J/psi Lambda branching ratio, and a high-statistics study of charm baryons.
