System Size and Centrality Dependence of the Electric Charge Correlations in A+A and p+p Collisions at the SPS Energies Original Research Article

The Balance Function analysis method was developed in order to study the long range correlations in pseudo-rapidity of charged particles. The final results on p+p, C+C, Si+Si and centrality selected Pb+Pb collisions at View the MathML source and the preliminary data at View the MathML source are presented. The width of the Balance Function decreases with increasing system size and centrality of the collisions. This could suggest a delayed hadronization scenario.
