“…Within the statistics, this ratio is independent of centrality. This behavior is similar to the K+/Kratio [6] which is also independent of centrality. In order to look for possible evidence of changes in the @mass due to interactions in the collision environment, the minimum bias data was divided at 1.4 GeV/c into two bins of ml; this value was chosen to give reasonable statistics in each bin.…”

The first measurements of@ meson production in Au-Au collisions at AGS energies are presented via the decay to If+ K-. A measurement of the centrality dependence of the yield shows an increase similar to that seen for the K-with a spectral shape consistent with a relativistic Breit-Wigner distribution within the statistical errors of the present data set. Future analysis using the full data set with 4 times the statistics will allow a more accurate determination of the yields, slopes and spectral shapes.

“…We have also reported in Fig. 5 the widths of the rapidity distributions of identified π + , π − , K + and K − measured by the E802 collaboration [33,34,35] in the 3%-5% most central Au-Au collisions at 11.6 GeV/c per nucleon and by the NA49 collaboration [20,23,36] in the 7% (resp. 5%) most central Pb-Pb collisions at 40 (resp.…”

The charged particle multiplicity distribution dN ch /dη has been measured by the NA50 experiment in Pb-Pb collisions at the CERN SPS. Measurements were done at incident energies of 40 and 158 GeV per nucleon over a broad impact parameter range. The multiplicity distributions are studied as a function of centrality using the number of participating nucleons (N part ), or the number of binary nucleon-nucleon collisions (N coll ). Their values at midrapidity exhibit a power law scaling behaviour given by N 1.00 part and N 0.75 coll at 158 GeV. Compatible results are found for the scaling behaviour at 40 GeV. The width of the dN ch /dη distributions is larger at 158 than at 40 GeV/nucleon and decreases slightly with centrality at both energies. Our results are compared to similar studies performed by other experiments both at the CERN SPS and at RHIC.

“…We note that, at this energy, there are no K + and K − yields measured in full phase space. Based on a comparison of the ratio K − /K + at mid-rapidity and in 4π at top AGS energy [53], we have assumed that at 6 AGeV the ratio K − /K + in 4π is 10% smaller than at mid-rapidity. At the top AGS energy, some of the 4π yields do not correspond to complete coverage [53]; also, the ratiop/p is obtained with a rather large extrapolation.…”

Hadron production in central nucleus–nucleus collisions at chemical freeze-out

We analyze the experimental hadron yield ratios for central nucleus-nucleus collisions in terms of thermal model calculations over a broad energy range, √ s N N =2.7-200 GeV. The fits of the experimental data with the model calculations provide the thermal parameters, temperature and baryo-chemical potential at chemical freezeout. We compare our results with the values obtained in other studies and also investigate more technical aspects such as a potential bias in the fits when fitting particle ratios or yields. Using parametrizations of the temperature and baryonic chemical potential as a function of energy, we compare the model calculations with data for a large variety of hadron yield ratios. We provide quantitative predictions for experiments at LHC energy, as well as for the low RHIC energy of 62.4 GeV. The relation of the determined parameters with the QCD phase boundary is discussed.
