Reanalysis of the heavy baryon states Ωb, Ωc, Ξ′b, Ξ′c, Σb and Σc with QCD sum rules

In this Letter, we re-study the heavy baryon states Omega(b), Omega(c), Xi'(b), Xi'(c), Sigma(b) and Sigma(c) with the QCD sum rules, after subtracting the contributions from the corresponding negative parity heavy baryon states, the predicted masses are in good agreement with the experimental data.
