Abstract

The NA49 experiment has collected comprehensive data on particle productionin nucleus-nucleus collisions over the whole SPS beam energies range, the critical energy domain where the expected phase transition to a deconfined phase is expected to occur. The latest results from Pb+Pb collisions between 20A GeV and 158A GeV on baryon stopping and light nuclei production as well as those for strange hyperons are presented. The measured data on p, p, Δ, Δ, and production were used to evaluate the rapidity distributions of net-baryons at SPS energies and to compare with the results from the AGS and the RHIC for central Pb+Pb (Au+Au) collisions. The dependence of the yield ratios and the inverse slope parameter of the m_t spectra on the collision energy and centrality, and the mass number of the produced nuclei ³He, t, d and d are discussed within coalescence and statistical approaches. Analysis of the total multiplicity exhibits remarkable agreement between the measured yield for ³He and those predicted by the statistical hadronization model. In addition, new results on Δ and Δ as well as production in minimum bias Pb+Pb reactions at 40A GeV and 158A GeV and central C+C, Si+Si and Pb+Pb collisions are presented. The system size dependence of the yields of these hyperons was analysed to determine the evolution of strangeness enhancement relative to elementary p+p collisions.

N2 - The NA49 experiment has collected comprehensive data on particle productionin nucleus-nucleus collisions over the whole SPS beam energies range, the critical energy domain where the expected phase transition to a deconfined phase is expected to occur. The latest results from Pb+Pb collisions between 20A GeV and 158A GeV on baryon stopping and light nuclei production as well as those for strange hyperons are presented. The measured data on p, p, Δ, Δ, and production were used to evaluate the rapidity distributions of net-baryons at SPS energies and to compare with the results from the AGS and the RHIC for central Pb+Pb (Au+Au) collisions. The dependence of the yield ratios and the inverse slope parameter of the mt spectra on the collision energy and centrality, and the mass number of the produced nuclei 3He, t, d and d are discussed within coalescence and statistical approaches. Analysis of the total multiplicity exhibits remarkable agreement between the measured yield for 3He and those predicted by the statistical hadronization model. In addition, new results on Δ and Δ as well as production in minimum bias Pb+Pb reactions at 40A GeV and 158A GeV and central C+C, Si+Si and Pb+Pb collisions are presented. The system size dependence of the yields of these hyperons was analysed to determine the evolution of strangeness enhancement relative to elementary p+p collisions.
