Query: Analysis of the $X(5568)$ as scalar tetraquark state in the
  diquark-antidiquark model with QCD sum rules   In this article, we take the $X(5568)$ as the diquark-antidiquark type
tetraquark state with the spin-parity $J^P=0^+$, construct the
scalar-diquark-scalar-antidiquark type current, carry out the operator product
expansion up to the vacuum condensates of dimension-10, and study the mass and
pole residue in details with the QCD sum rules. We obtain the value
$M_X=\left(5.57\pm0.12 \right) \,\rm{GeV}$, which is consistent with the
experimental data. The present prediction favors assigning the $X(5568)$ to be
the scalar tetraquark state.
