Calculation of heavy ion collisions within the framework of the modified hydrodynamic approach

Abstract

We developed the hydrodynamic approach to describe heavy ion collisions of medium energy, allowing for the emission of secondary particles. The compression, decompression and freeze-out stages of the forming hot spot have been examined. The shock wave that appears in the compression stage has a time dependent front. The calculated spectra of protons have been compared with experimental data. Due to its simplicity, the model can be used for a convenient parameterization of the experimental data.
