Figure 1
Efficiency-corrected spectra for the indicated particle types and centrality bins in Au+Au collisions at GeV. Note that seven centrality bins have been used for and while only six and three have been used for and , respectively. Only statistical uncertainties are shown. The spectra are corrected for the feed-down from decay. The dashed lines are fits to the spectra with a Maxwell-Boltzmann function.

Statistical uncertainties are represented by the bars while the systematic uncertainties are represented by the gray bands. The , and data were extracted from Ref. [1]. Some data points are shifted in the horizontal direction for visibility.

The AGS values are from E896 [2] (centrality 0%–5%). The SPS values are from NA49 [3] (centrality 0%–7%) and the RHIC values are from STAR [4, 5] (centrality 0%–5%). For the multistrange baryons and (bottom panel), the SPS results are from NA57 [6] (centrality 0%–11%) and the RHIC values are from STAR [5, 7] (centrality 0%–20%). The bars indicate only the statistical uncertainties for the STAR data points.

Antibaryon to baryon yield ratios for strange baryons in central Au+Au and Pb+Pb collisions versus the center of mass energy . is shown in the top panel while ratios for the multistrange baryons are in the bottom panel. The data from AGS are not corrected for the weak decay feed-down from the multistrange baryons while the data from SPS and RHIC are corrected. The lines are the results of the thermal model calculation (see Sec. IV A of the original article). The AGS values are from E896 [2] (centrality 0%–5%). The SPS values are from NA49 [3] (centrality 0%–7%) and the RHIC values are from STAR [4, 5] (centrality 0%–5%).

The values were extracted from Ref. [8]. The vertical bars around the markers indicate only the statistical uncertainties. The gray band on the right side of the plot shows the uncertainty on the scaling by the number of binary collisions. The gray band on the lower left side indicates the uncertainty on the scaling by the number of participants. The solid and dashed lines inside these bands are the baselines of the scalings by the number of binary collisions and the number of participants, respectively.
