Query: Determination of the spectroscopic parameters of beauty-partners of
  $T_{cc}$ from QCD   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 $BB^*$ picture. The
obtained results are compared with the predictions of different approaches in
the literature.
