Abstract

Forward–backward (FB) charge correlations are investigated by analyzing experimental data on 16 O – AgBr interactions at 14.5A, 60A and 200A GeV . Findings are compared with the predictions of Monte Carlo model, heavy-ion jet interaction generater (HIJING). The results reveal that the observed correlations are mainly of short-range type, which arise due to the decay of clusters and/or resonances produced in the central rapidity region. The range of FB correlations are observed to extend with increasing beam energy. However, there is no evidence for the presence of long-range correlations even at the highest incident energy considered.
