In this article, we study the 1/2(-) and 3/2(-) heavy and doubly heavy baryon states Sigma(Q)(1/2(-)), Xi'(Q) (1/2(-)), Omega Q(1/2(-)), Xi(QQ)(1/2(-)), Omega(QQ)(1/2(-)), Sigma*(Q)(3/2(-)), Xi*(Q)(3/2(-)), Omega*Q(3/2(-)), Xi*(QQ)(3/2(-)) and Omega*(QQ)(3/2(-)) by subtracting the contributions from the corresponding 1/2(+) and 3/2(+) heavy and doubly heavy baryon states with the QCD sum rules in a systematic way, and make reasonable predictions for their masses.
