Search for Long-Range Correlations in Relativistic Heavy-Ion Collisions at SPS Energies

Search for Long-Range Correlations in Relativistic Heavy-Ion Collisions at SPS Energies

Long-range correlations are searched for by analysing the experimental data on 16O-AgBr and 32S-AgBr collisions at 200 A GeV/c and the results are compared with the predictions of a multi phase transport (AMPT) model. The findings reveal that the observed forward-backward (F-B) multiplicity correl...
