Experimental Results on Charge Fluctuations in Heavy-Ion Collisions

Figure 5

Energy dependence of net-charge fluctuations about midrapidity in central heavy-ion collisions at SPS [52], RHIC [51], and LHC [53] energies. Also shown are the expectations from a hadron resonance gas model and for a simple QGP picture [22]. The combined (statistical and systematic) errors are plotted along with the data points.
