Abstract:
In a few previous works we analyzed the competition between different particle production mechanisms in nucleus–nucleus collisions at 4.5 A GeV/c, like: hydrodynamic models, thermodynamic models, intranuclear cascades and cumulative production. We found hydrodynamic specific effects (the bounce-off of the projectile and of target spectator fragments and the squeeze–out or the splash–out of participant matter), as well as jets of nuclear matter. In this work we made a comparison of the characteristics of nuclear matter jets from He+AT relativistic nuclear collisions (SKM200 JINR Dubna Collaboration) and the nuclear matter jets detected in simulated collisions with the GEANT4 simulator. The results show us a similitude of properties (momentum distributions, angular distributions, etc.) of real and simulated jets. At this energy of projectile the mechanism of interaction seems to be the intranuclear cascades one. The nonjet events present some different properties, indicating collective phenomena.
