Mass splitting of heavy-baryons from QCD sum rules
We extract the heavy-baryons mass-splittings due to S U (3) breaking using double ratios of QCD sum rules. We evaluate the masses of the strange-heavy baryons ΞQ , Ξ*Q , ΩQ and Ω*Q using as input the masses of the associated non-strange ΛQ , ΣQ and Σ*Q baryons. We notice that the leading term...
