The Balance Function analysis method was developed in order to study the long range correlations in pseudo-rapidity of charged particle. The final results on p+p, C+C, Si+Si and centrality selected Pb+Pb collisions at $sqrt{s_{NN}} = 17.2$ GeV and the preliminary data at $sqrt{s_{NN}} = 8.8$ GeV 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.
Results from electric charge correlations studied with the Balance Function method in A+A collisions from 20emph{A} to 158emph{A} GeV are presented in two different rapidity intervals: In the mid-rapidity region we observe a decrease of the width of
Electric charge correlations are studied with the Balance Function method for central Pb + Pb collisions at the CERN - SPS. The results on centrality selected Pb + Pb interactions at 40 and 158 AGeV are presented for the first time for two different
Results are presented of a two-pion interferometry (HBT) analysis in Pb+Au collisions at 40, 80, and 158 AGeV. A detailed study of the Bertsch-Pratt HBT radius parameters has been performed as function of the mean pair transverse momentum $k_t$ and i
The elliptic and triangular flow coefficients ($mathrm{v_n, , n=2,3}$) measured in Pb+Pb ($sqrt{s_{_{rm NN}}} = 2.76$ TeV) and p+Pb ($sqrt{s_{_{rm NN}}} = 5.02$ TeV) collisions, are studied as a function of initial-state eccentricity ($varepsilon_n$)
First results are presented from BNL experiment E910 on pion production and stopping in proton-Be, Cu, and Au collisions at a beam momentum of 18 GeV/c. We characterize the centrality of the collisions using the measured number of grey tracks, Ngrey,
