Abstract: We calculate the masses and residues of triply heavy baryons with spin-3/2, including Ω c c c * , Ω c c b * , Ω b b c * and Ω b b b * , using the QCD sum rules method. Our calculations primarily focus on obtaining the masses of the first three resonances, that is, the ground state (1S), the first orbital excited state (1P), and the first radial excited state (2S), for the mentioned baryons. We additionally determine the residues of these baryons, which serve as key parameters for studying their possible decay channels and interactions with other particles. To achieve higher accuracy compared to previous studies, we consider nonperturbative operators up to eight mass dimensions. We present our calculated outcomes in two distinct energy schemes, referred to as pole and MS ‾ . Given the absence of experimental data for these states, we compare our results with previous theoretical calculations that are reported in relevant studies employing various approaches. These results may provide valuable insights for experimental groups searching for the triply heavy baryons.
