Abstract: We perform a systematic study of the masses of charmed and bottom baryons inthe framework of the QCD sum rule approach. Contributions of the operators upto dimension six are included in operator product expansion. The resultingheavy baryon masses from the calculations are well consistent with theexperimental values, and predictions to the spectroscopy of the unobservedbottom baryons are also presented.
