Abstract

Within the framework of the QCD sum rules method, the masses and pole residues of the excited states 2S and 1P of the doubly-heavy spin-(3/2) baryons ${\mathrm{\Xi }}_{\mathit{cc}}^{\ast }$, ${\mathrm{\Xi }}_{\mathit{bb}}^{\ast }$, ${\mathrm{\Xi }}_{\mathit{bc}}^{\ast }$, ${\mathrm{\Omega }}_{\mathit{cc}}^{\ast }$, ${\mathrm{\Omega }}_{\mathit{bb}}^{\ast }$, and ${\mathrm{\Omega }}_{\mathit{bc}}^{\ast }$ are investigated. The excited state masses and pole residues are predicted with reasonable accuracy. We expect that soon, the current predictions can be tested against future experimental data.
