N2 - Experiments at the Juelich Cooler Synchrotron (COSY) have now found compelling evidence for a new state in the two-baryon system with mass 2380 MeV and width 70 MeV. The structure, containing six valence quarks, constitutes a so-called dibaryon, either a hexaquark or a hadronic molecule. The new particle denoted now d*(2380) has quantum numbers I(Jp) = 0(3+). The present knowledge about the d* dibaryon as well as other implications and possible future experiments are discussed. Di-baryonic systems with strangeness, like K-pp or hypothetical H-dibaryon are outside the scope of this paper.
