  Experiments at the Juelich Cooler Synchrotron (COSY) have now found
compelling evidence for a new resonant state in the two-baryon system with mass
2380 MeV and a width of 70 MeV. The structure, containing six valence quarks,
constitutes a so-called dibaryon, either a hexaquark or a hadronic molecule.
The present knowledge about the dibaryon as well as other implications and
possible future experiments are discussed.
