Cascade production in heavy-ion collisions at SIS energies Academic Article uri icon

abstract

  • Production of the doubly strange baryon in heavy-ion collisions at SIS energies is studied in a relativistic transport model that includes perturbatively the strangeness-exchange reactions K and K. Taking the cross sections for these reactions from the predictions of a hadronic model, we find that the yield is about 10-4 in central collisions of 58Ni+58Ni at E/A=1.93 GeV. The yield is further found to be more sensitive to the magnitude of the cross sections for strangeness-exchange reactions than to the medium effects due to modified kaon properties. We have also made predictions for production in Au+Au collisions at energies from 1 to 2 GeV/nucleon. 2004 Elsevier B.V. All rights reserved.
