Determination of the spectroscopic parameters of beauty-partners of $T_{cc}$ from QCD

Abstract

Motivated by the recent discovery of a new tetra-quark $T_{cc}^{+}$ 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 by using hadronic molecular $B{B}^{\ast }$ picture. The obtained results are compared with the predictions of different approaches in the literature.
