Özet

We study a hypothetical A0A0 dibaryon state by means of the QCD sum rule method. We construct a scalar interpolating current to extract the mass and decay constant of this state taking into account contributions of various quark, gluon, and mixed vacuum condensates. The predictions for the mass and decay constants are mD = 2326+114???126 MeV and fD = 2.94+0.30 an estimation about binding energy and size of the A0A0 dibaryon. The obtained mass value is below the A0A0 threshold and may be a good dibaryon candidate for being observed experimentally.
