Reaction dynamics in Pb+Pb at the CERN/SPS: from partonic degrees of freedom to freeze-out
S. A. Bass, H. Weber, C. Ernst +7
We analyze the reaction dynamics of central Pb+Pb collisions at 160 GeV/nucleon. First we estimate the energy density pile-up at mid-rapidity and calculate its excitation function:…
Local Thermal and Chemical Equilibration and the Equation of State in Relativistic Heavy Ion Collisions
L. V. Bravina, M. Brandstetter, M. I. Gorenstein +9
Thermodynamical variables and their time evolution are studied for central relativistic heavy ion collisions from 10.7 to 160 AGeV in the microscopic Ultrarelativistic Quantum Mole…
Excitation Function of Energy Density and Partonic Degrees of Freedom in Relativistic Heavy Ion Collisions
H. Weber, C. Ernst, M. Bleicher +5
We estimate the energy density pile-up at mid-rapidity in central Pb+Pb collisions from 2 - 200 GeV/nucleon. The energy density is decomposed into hadronic and partonic contributio…
Local Thermodynamical Equilibrium and the Equation of State of Hot, Dense Matter Created in Au+Au Collisions at AGS
L. V. Bravina, M. I. Gorenstein, M. Belkacem +9
Local kinetic and chemical equilibration is studied for Au+Au collisions at 10.7 AGeV in the microscopic Ultrarelativistic Quantum Molecular Dynamics model (UrQMD). The UrQMD model…
Equation of State, Spectra and Composition of Hot and Dense Infinite Hadronic Matter in a Microscopic Transport Model
M. Belkacem, M. Brandstetter, S. A. Bass +10
Equilibrium properties of infinite relativistic hadron matter are investigated using the Ultrarelativistic Quantum Molecular Dynamics (UrQMD) model. The simulations are performed i…
Microscopic Models for Ultrarelativistic Heavy Ion Collisions
S. A. Bass, M. Belkacem, M. Bleicher +18
In this paper, the concepts of microscopic transport theory are introduced and the features and shortcomings of the most commonly used ansatzes are discussed. In particular, the Ul…
