Kinetic equation for gluons at the early stage
Qun Wang, Krzysztof Redlich, Horst Stöcker +1
We derive the kinetic equation for pure gluon QCD plasma in a general way, applying the background field method. We show that the quantum kinetic equation contains a term as in the…
Black Hole Production in Large Extra Dimensions at the Tevatron: Possibility for a First Glimpse on TeV Scale Gravity
Marcus Bleicher, Stefan Hofmann, Sabine Hossenfelder +1
The production of black holes in large extra dimensions is studied for Tevatron energies. We find that black holes may have already been created in small abundance in co…
Kinetic Equation for Gluons in the Background Gauge of QCD
Q. Wang, K. Redlich, H. Stöcker +1
We derive the quantum kinetic equation for a pure gluon plasma, applying the background field and closed-time-path method. The derivation is more general and transparent than earli…
Partonic Scattering Cross Sections in the QCD Medium
Joerg Ruppert, Gouranga C. Nayak, Dennis D. Dietrich +2
A medium modified gluon propagator is used to evaluate the scattering cross section for the process gg-->gg in the QCD medium by performing an explicit sum over the polarizations o…
Space-time evolution and HBT analysis of relativistic heavy ion collisions in a chiral SU(3) x SU(3) model
D. Zschiesche, S. Schramm, H. Stoecker +1
The space-time dynamics and pion-HBT radii in central heavy ion-collisions at CERN-SPS and BNL-RHIC are investigated within a hydrodynamic simulation. The dependence of the dynamic…
Microscopic coloured quark-dynamics in the soft non-perturbative regime -- Description of hadron formation in relativistic S+Au collisions at CERN
S. Scherer, M. Hofmann, M. Bleicher +3
The quark-molecular-dynamics model is used to study microscopically the dynamics of the coloured quark phase and the subsequent hadron formation in relativistic S+Au collisions at…
Nuclei, Superheavy Nuclei and Hypermatter in a chiral SU(3)-Modell
Ch. Beckmann, P. Papazoglou, D. Zschiesche +3
A model based on chiral SU(3)-symmetry in nonlinear realisation is used for the investigation of nuclei, superheavy nuclei, hypernuclei and multistrange nuclear objects (so called…
J/psi Suppression and Enhancement in Au+Au Collisions at the BNL RHIC
M. I. Gorenstein, A. P. Kostyuk, H. Stoecker +1
We consider the production of the J/psi mesons in heavy ion collisions at RHIC energies in the statistical coalescence model with an exact (canonical ensemble) charm conservation.…
Damping scales of neutralino cold dark matter
Stefan Hofmann, Dominik J. Schwarz, 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…
Nuclear Broadening Effects on Hard Prompt Photons at Relativistic Energies
A. Dumitru, L. Frankfurt, L. Gerland +2
We calculate prompt photon production in high-energy nuclear collisions. We focus on the broadening of the intrinsic transverse momenta of the partons in the initial state from nuc…
Strange quark stars within the Nambu-Jona-Lasinio model
M. Hanauske, L. M. Satarov, I. N. Mishustin +2
We investigate the properties of charge-neutral -equilibrium cold quark matter within the Nambu-Jona-Lasinio model. The calculations are carried out for different ratios of coup…
