Centrality Dependence of Multiplicity Fluctuations from a Hydrodynamical Approach

Figure 1

The centrality dependence of the calculated dynamical fluctuations of particle ratio , , and for Au+Au collisions at 200 GeV. The STAR data are from Ref. [26], presented by filled, open, half-filled red stars. The SPheRIO results are given by the filled, open, half-filled blue circle. The UrQMD model calculations are shown in the filled, open, half-filled green triangle. The dashed black line presents the HRG calculations.
