Experimental Results on Charge Fluctuations in Heavy-Ion Collisions

Figure 1

The relative fluctuations, , of the event-by-event measured charged particle multiplicity as a function of number of participants () in Pb + Pb collisions at 158 AGeV [40]. The combined (statistical and systematic) errors on from the experimental data are shown along with the data points. Details on error estimation are in [40]. The experimental data are compared to calculations from a participant model and those from VENUS event generator.
