Abstract: | The implications of parton rearrangement processes on the dynamics of ultra-relativistic heavyion collisions have been investigated.
A microscopic transport approach, namely the quark gluon string model (QGSM) which has been extended for a locally density-dependent
partonic rearrangement and fusion procedure served as the tool for this investigations. The model emulates effectively the
dynamics of a strongly coupled quark plasma and final hadronic interactions. Main QGSM results on anisotropic flow components
v
1 and v
2 at top RHIC energy are compiled. Predictions for the pseudorapidity dependence of directed and elliptic flow in Pb+Pb collisions
under LHC conditions are presented. |
