Query: Pseudorapidity dependence of short-range correlations from a multi-phase
  transport model   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
$\sqrt{s_{NN}} = 7.7-62.4$ GeV. It is observed that for $\sqrt{s_{NN}} <
$19.6GeV Au+Au collisions, the short-range correlations of final particles have
a trough at central pseudorapidity, while for $\sqrt{s_{NN}} > $19.6GeV 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.
