Description
Weakly decaying bottom baryons can in principle be clearly reconstructed from
their decays into J/psi or other charmed hadrons. However, their
properties like lifetimes and branching fractions have long been quoted
only as averages over all states, as the only directly observed b-baryon
was the Lambda_b. Only in year 2007, the two Tevatron experiments observed
the Xi_b, and recently the D0 collaboration observed also the Omega_b.
With the growing dataset accumulated by the Tevatron, it is becoming
possible to study the properties of the b-baryons in more detail. In this
talk we present a study of production and properties of the Xi_b and
Omega_b baryons using 4.2 fb-1 of data accumulated by the CDF II
experiment.
