Abstract：
Using a multi-phase transport model (AMPT) that includes both initial partonic and hadronic interactions, we study neighboring bin multiplicity correlations as a function of pseudorapidity in Au+Au collisions at √^SNN = 7.7-62.4 GeV. It is observed that for √^SNN < 19.6 GeV Au+Au collisions, the short-range correlations of final particles have a trough at central pseudorapidity, while for √^SNN > 19.6 GeV AuAu collisions, the short-range correlations of final particles have a peak at central pseudorapidity. Our findings indicate that the pseudorapidity dependence of short-range correlations should contain some new physical information, and are not a simple result of the pseudorapidity distribution of final particles. The AMPT results with and without hadronic scattering are compared. It is found that hadron scattering can only increase the short-range correlations to some level, but is not responsible for the different correlation shapes for different energies. Further study shows that the different pseudorapidity dependence of short-range correlations are mainly due to partonic evolution and the following hadronization scheme.
- short-range correlations ,
- hadronic interaction ,
- partonic evolution ,
- hadronization scheme
