Abstract

The Juelich Cooler Synchrotron (COSY) has been dedicated to the investigation of nucleon-nucleon interactions. Together with the Wide Angular Shower Apparatus (WASA) detector, it has been particularly well-suited for the search of exotic phenomena in baryon-baryon systems. Recent experiments with WASA-at-COSY have now found support for a new resonant state in the two-baryon system with mass 2380 MeV and a width of 70 MeV - the first non-trivial dibaryon resonance. A review on this issue is given in this paper.
