Are we close to the QGP? - Hadrochemical vs. microscopic analysis of particle production in ultrarelativistic heavy ion collisions
S. A. Bass, M. Belkacem, M. Brandstetter +9
Ratios of hadronic abundances are analyzed for pp and nucleus-nucleus collisions at sqrt(s)=20 GeV using the microscopic transport model UrQMD. Secondary interactions significantly…
Direct photons in Pb+Pb at CERN-SPS from microscopic transport theory
A. Dumitru, M. Bleicher, S. A. Bass +4
Direct photon production in central Pb+Pb collisions at CERN-SPS energy is calculated within the relativistic microscopic transport model UrQMD, and within distinctly different ver…
Phase transition of a finite quark-gluon plasma
C. Spieles, H. Stoecker, C. Greiner
The deconfinement transition region between hadronic matter and quark-gluon plasma is studied for finite volumes. Assuming simple model equations of state and a first order phase t…
Hadron and hadron-cluster production in a hydrodynamical model including particle evaporation
A. Dumitru, C. Spieles, H. Stoecker +1
We discuss the evolution of the mixed phase at RHIC and SPS within boostinvariant hydrodynamics. In addition to the hydrodynamical expansion, we also consider evaporation of partic…
A microscopic calculation of secondary Drell-Yan production in heavy ion collisions
C. Spieles, L. Gerland, N. Hammon +6
A study of secondary Drell-Yan production in nuclear collisions is presented for SPS energies. In addition to the lepton pairs produced in the initial collisions of the projectile…
Search for Production of Strangelets in Quark Matter using Particle Correlations
Sven Soff, D. Ardouin, C. Spieles +9
We present a new technique for observing the strangelet production in quark matter based on unlike particle correlations. A simulation is presented with a two-phase thermodynamical…
