Determination of the spectroscopic parameters of beauty-partners of T-cc from QCD

Motivated by the recent discovery of a new tetraquark T-cc(+) state with two charm quarks and two light quarks by LHCb Collaboration, we calculate the spectroscopic parameters; namely, the mass and residues of beauty partners of T-cc(+) within QCD sum rules. The obtained results are compared with the predictions of different approaches in the literature.
