Subthreshold K meson and antiproton production in the nucleus-nucleus collisions within the framework of the fluid dynamics approach
A T D'yachenko
Show affiliationsProduction of K mesons and antiprotons in heavy ion collisions is considered at energies below the production threshold in the free nucleon-nucleon collisions. A simple nuclear fluid dynamics model was used to describe the experimental data. The calculation reproduces the experimental energy spectra of the subthreshold kaons and antiprotons at various energies and various combinations of the colliding nuclei. For strange particles and antiparticles the associative character of the production was taken into account, which considerably reduced the absolute value of the production cross section.
