The mass differences in the baryon octet with J/sup p/ = 1/2 /sup +/, decuplet with J/sup p/ = (3)/(2) /sup +/, and octet with J/sup p/ = (3)/(2) /sup -/ are calculated on the basis of the quantum-chromodynamics (QCD) sum rules. The mass differences are expressed in terms of two QCD parameters: the mass of the current strange quark and the value of the quark condensate <0Vertical Bars-barsVertical Bar0>. When these parameters are suitably chosen, all the mass differences agree well with experiment.
