Observing compact quark matter droplets in relativistic nuclear collisions
K. Paech, J. Brachmann, M. A. Lisa +3
Compactness is introduced as a new method to search for the onset of the quark matter transition in relativistic heavy ion collisions. That transition supposedly leads to stronger…
Excitation function of entropy and pion production from AGS to SPS energies
M. Reiter, A. Dumitru, J. Brachmann +3
Entropy production in the initial compression stage of relativistic heavy-ion collisions from AGS to SPS energies is calculated within a three-fluid hydrodynamical model. The entro…
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…
``Soft'' transverse expansion and flow in a multi-fluid model without phase transition
J. Brachmann, A. Dumitru, M. Bleicher +3
We study transverse expansion and directed flow in Au(11AGeV)Au reactions within a multi-fluid dynamical model. Although we do not employ an equation of state (EoS) with a first or…
``Pressure Equilibration'' in Ultrarelativistic Heavy Ion Collisions
J. Brachmann, A. Dumitru, C. Spieles +3
We study the time scale for pressure equilibration in heavy ion collisions at AGS energies within the three-fluid hydrodynamical model and a microscopic cascade model (UrQMD). We f…
Extracting the equation of state from a microscopic non-equilibrium model
C. Spieles, A. Dumitru, S. A. Bass +12
We study the thermodynamic properties of infinite nuclear matter with the Ultrarelativistic Quantum Molecular Dynamics (URQMD), a semiclassical transport model, running in a box wi…
