Abstract
The mass and current-meson coupling constant of the exotic X(3872) state are computed within the two-point sum rule method using the diquark-antidiquark and molecule interpolating currents. In calculations the quark, gluon and mixed vacuum condensates up to ten dimensions are taken into account. Within the diquark-antidiquark picture for the mass of the X(3872) state we obtain m_X = 3873 MeV, which is very close to the experimental result of the Belle Collaboration. The molecule model leads for m_X to the prediction that slightly exceeds the experimental data. We compare our predictions for the mass and coupling constant with available experimental data and other theoretical results.
