Properties of the ground and excited states of triply heavy spin-1/2 baryons

We study the triply heavy spin-1/2 baryons with quark contents ccb and bbc , and calculate their mass and residue using QCD sum rules. In the calculations, we consider the ground (1 S), first orbitally excited (1P) and first radially excited (2 S) states. Aiming to achieve higher accuracies in the r...

Description
Summary:We study the triply heavy spin-1/2 baryons with quark contents ccb and bbc , and calculate their mass and residue using QCD sum rules. In the calculations, we consider the ground (1 S), first orbitally excited (1P) and first radially excited (2 S) states. Aiming to achieve higher accuracies in the results, we perform the computations by taking into account the non-perturbative operators up to eight mass dimensions. We compare our results with the predictions of other theoretical studies existing in the literature. The obtained results may help experimental groups in their search for these yet unseen, but previously predicted by the quark model, interesting particles.
