On Dynamical Net-Charge Fluctuations within a Hadron Resonance Gas Approach

Figure 1

The energy dependence of the dynamical net-charge fluctuations calculated from the HRG model is compared with STAR [25] (solid symbols) and NA49 [34] (open triangles) measurements for the charge ratios (a), (b), and (c). The fluctuations of the charge ratios are determined as total and average of the same and average of opposite charge-signs.
