Emission of Cumulative Protons, Pions, Kaons, and Antiprotons in Collisions of Heavy Ions of Intermediate Energies Based on Non-Equilibrium Hydrodynamic Approach

A successful description of the double differential cross sections for the emission of cumulative protons, pions, kaons and antiprotons in collisions of carbon nuclei on a fixed target at an energy of 19.6 GeV/nucleon was obtained in the IHEP experiment (Serpukhov) at the U-70 accelerator. When describing these spectra, the nonequilibrium approach was taken into account as a result of the joint solution of the kinetic equation with the equations of hydrodynamics. Comparisons with other reactions and approaches are made.
