Özet

The mass and decay constant of the X(5568) state newly observed by the D0 Collaboration are computed within the two-point sum rule method using the diquark-antidiquark interpolating current. In calculations, the vacuum condensates up to eight dimensions are taken into account. The obtained result for the mass of the X(5568) state is in a nice agreement with the experimental data.
