On the Theoretical Interpretation of the Data on Collisions of Argon Nuclei with Various Nuclei at High Energies

Year: 2024

Type: article

Abstract: Recently (2024), the NA61/SHINE collaboration has presented new experimental data on $${{\pi }^{ \pm }}$$ , $${{K}^{ \pm }}$$ , proton, and antiproton productions in central 40Ar + 45Sc collisions at the laboratory momenta P lab = 13–150 A GeV/c and has compared these data with predictions of popular theoretical models. It turned out that the models poorly describe the data in the entire energy range. In this work, it has been suggested for the first time that nucleons participating in non-diffractive collisions cannot diffractively dissociate in subsequent nucleon–nucleon collisions. This idea has been implemented in the Geant4 FTF model. Good description of the data, including the first NICA BM@N data on $${{\pi }^{ + }}$$ meson production in the collisions of 40Ar nuclei with various nuclei at an energy of 3.2 A GeV, has been achieved.
