Probing Hadronization with Strangeness
S. A. Bass, M. Bleicher, J. Aichelin +5
The Omega-bar/Omega ratio originating from string decays is predicted to be larger than unity in proton-proton interaction at SPS energies. The anti-omega dominance increases with…
Transport calculation of dilepton production at ultrarelativistic energies
C. Ernst, S. A. Bass, S. Soff +2
Dilepton spectra are calculated within the microscopic transport model UrQMD and compared to data from the CERES experiment. The invariant mass spectra in the region 300 MeV < M <…
RHIC predictions from the UrQMD model
M. Bleicher, S. A Bass, H. Stöcker +1
The Ultra-relativistic Quantum-Molecular-Dynamics model (UrQMD) is used to study central Pb+Pb reactions at RHIC ( AGeV). The computed collision spectrum reveals that…
Directed and Elliptic Flow
Sven Soff, Steffen A. Bass, Marcus Bleicher +2
We compare microscopic transport model calculations to recent data on the directed and elliptic flow of various hadrons in 2 - 10 A GeV Au+Au and Pb (158 A GeV) Pb collisions. For…
J/psi suppression in heavy ion collisions - interplay of hard and soft QCD processes
C. Spieles, R. Vogt, L. Gerland +6
We study J/psi suppression in AB collisions assuming that the charmonium states evolve from small, color transparent configurations. Their interaction with nucleons and nonequilibr…
Microscopic Analysis of Thermodynamic Parameters from 160 MeV/n - 160 GeV/n
M. Bleicher, S. A. Bass, M. Belkacem +10
Microscopic calculations of central collisions between heavy nuclei are used to study fragment production and the creation of collective flow. It is shown that the final phase spac…
