HSD Transport Model as a Tool for Studying Fluctuations in Nucleus-Nucleus Collisions

  • Conference paper
Progress in HighEnergy Physics and Nuclear Safety

Abstract

The multiplicity fluctuations in nucleus-nucleus collisions at SPS and RHIC energies within the HSD transport approach and statistical model have been studied. Both energy and system size dependences of the scaled variances have been analyzed for proton—proton and central nucleus—nucleus collisions. The importance of rigid centrality trigger has been discussed additionally.
