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…
Damping of inhomogeneities in neutralino dark matter
Dominik J. Schwarz, Stefan Hofmann, Horst Stoecker
The lightest supersymmetric particle, most likely the neutralino, might account for a large fraction of dark matter in the Universe. We show that the primordial spectrum of density…
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…
Irreversibility, steady state, and non-equilibrium physics in relativistic heavy ion collisions
E. E. Zabrodin, L. V. Bravina, H. Stoecker +1
Heavy ion collisions at ultrarelativistic energies offer the opportunity to study the irreversibility of multiparticle processes. Together with the many-body decays of resonances,…
J/psi suppression in heavy ion collisions - interplay of hard and soft QCD processes
C. Spieles, R. Vogt, L. Gerland +6
We study J/psi suppression in AB collisions assuming that the charmonium states evolve from small, color transparent configurations. Their interaction with nucleons and nonequilibr…
