In this article, we study the masses and pole residues of the flavor antitriplet heavy baryon states (, and (, by subtracting the contributions from the corresponding heavy baryon states with the QCD sum rules, and observe that the masses are in good agreement with the experimental data and make reasonable predictions for the unobserved bottom baryon states. Once reasonable values of the pole residues λ Λ and λ Ξ are obtained, we can take them as basic parameters to study the relevant hadronic processes with the QCD sum rules.
