Jet Tomography Studies in AuAu Collisions at RHIC Energies

Recent RHIC results on pion production in AuAu collision at √ s = 130 and 200 AGeV display a strong suppression effect at high pT . This suppression can be connected to final state effects, namely jet energy loss induced by the produced dense colored matter. Applying our pQCD-based parton model we perform a quantitative analysis of the measured suppression pattern and determine the opacity of t...

Multiphase transport model for relativistic nuclear collisions

To study heavy ion collisions at energies available from the Relativistic Heavy Ion Collider ~RHIC!, we have developed a multiphase transport model that includes both initial partonic and final hadronic interactions. Specifically, the Zhang’s parton cascade ~ZPC! model, which uses as input the parton distribution from the heavy ion jet interaction generator ~HIJING! model, is extended to includ...

Uranium on uranium collisions at relativistic energies

Deformation and orientation effects on compression, elliptic flow and particle production in uranium on uranium collisions (UU) at relativistic energies are studied within the transport model ART. The density compression in tip-tip UU collisions is found to be about 30% higher and lasts approximately 50% longer than in body-body or spherical UU reactions. The body-body UU collisions have the un...

Hadronic centrality dependence in nuclear collisions

The kaon number density in nucleus+nucleus and p+p reactions is investigated for the first time as a function of the initial energy density ǫ and is found to exhibit a discontinuity around ǫ=1.3 GeV/fm. This suggests a higher degree of chemical equilibrium for ǫ > 1.3 GeV/fm. It can also be interpreted as reflection of the same discontinuity, appearing in the chemical freeze out temperature (T)...
