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 <…
Rho Meson Broadening in Hot and Dense Hadronic Matter
Song Gao, Charles Gale, Christoph Ernst +2
The modification of the width of rho mesons due to in-medium decays and collisions is evaluated. The decay width is calculated from the imaginary part of the one-loop self-energy a…
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…
Signatures of dense hadronic matter in ultrarelativistic heavy ion reactions
L. A. Winckelmann, C. Ernst, L. Gerland +13
The behavior of hadronic matter at high baryon densities is studied within Ultrarelativistic Quantum Molecular Dynamics (URQMD). Baryonic stopping is observed for Au+Au collisions…
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…
Nucleus-Nucleus Collisions at Highest Energies
M. Bleicher, N. Amelin, S. A. Bass +10
The microscopic phasespace approach URQMD is used to investigate the stopping power and particle production in heavy systems at SPS and RHIC energies. This framework bridges with o…
