Evidence for psi' Regeneration in Heavy Ion Collisions
Andriy Kostyuk, Horst Stoecker
The production of the psi' meson in Pb+Pb collisions at CERN SPS is analyzed. It provides an evidence for charmonium regeneration via charm quark-antiquark coalescence at hadroniza…
Superheavy Nuclei in a Chiral Hadronic Model
Ch. Beckmann, P. Papazoglou, D. Zschiesche +3
Superheavy nuclei are investigated in a nonlinear chiral SU(3)-model. The proton number Z=120 and neutron numbers of N=172, 184 and 198 are predicted to be magic. The charge distri…
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…
Collective flow in heavy ion reactions and the properties of excited nuclear matter
J. Konopka, S. A. Bass, M. Bleicher +8
Quantum Molecular Dynamics (QMD) calculations of central collisions between heavy nuclei are used to study fragment production and the creation of collective flow. It is shown that…
Microscopic calculation of expanding nuclear matter
Jens Konopka, Horst Stoecker, Walter Greiner
Quantum Molecular Dynamics (QMD) calculations are used to study the expansion phase in central collisions between heavy nuclei. The final state of such a reaction can be understood…
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…
