SEARCH FOR DIBARYONIC DE-EXCITATIONS IN RELATIVISTIC NUCLEAR-REACTIONS

Some odd characteristics are observed in the single-particle distribut ions obtained from He + Li interactions at 4.5 AGeV c(-1) momenta whic h are explained as the manifestation of a new mechanism of strangeness production via dibaryonic de-excitations. A signature of the formatio n of hadronic and baryonic clusters is also reported. The dipionic sig nals of the dibaryonic orbital de-excitations are analysed in the cont ext of the MIT bag model and a Monte Carlo simulation. The role played by the dibaryonic resonances in relativistic nuclear collisions could be a significant one.
