pi-/pi+ ratio in heavy ions collisions: Coulomb effect or chemical equilibration?
N. Arbex, U. Ornik, M. Pluemer +2
We calculate the pi-/pi+ ratio for Pb+Pb at CERN/SPS energies and for Au+Au at BNL/AGS energies using a (3+1) dimensional hydrodynamical model. Without consideration of Coulomb eff…
Hydrodynamical analysis of symmetric nucleus-nucleus collisions at CERN/SPS energies
U. Ornik, M. Plümer, B. R. Schlei +2
We present a coherent theoretical study of ultrarelativistic heavy-ion data obtained at the CERN/SPS by the NA35/NA49 Collaborations using 3+1-dimensional relativistic hydrodynamic…
Hydrodynamical analysis of single inclusive spectra and Bose-Einstein correlations for at 160 AGeV
B. R. Schlei, U. Ornik, M. Plümer +2
We present the first analysis of preliminary data for at 160 using 3+1-dimensional relativistic hydrodynamics. We find excellent agreement with the rapidity spectra…
Pre-Equilibrium Stage and Phase Transition of Quark Matter Probed by Photon Interferometry
U. Ornik, M. Plumer, A. Timmermann +1
We study single- and double-inclusive spectra of thermal photons, produced in heavy-ion collisions at AGeV within a realistic space-time framework which combines the…
Coherent Bremsstrahlung Emission in the Early Stage of Relativistic Heavy Ion Collisions
C. Bertulani, L. Mornas, U. Ornik
We present a model of coherent Bremsstrahlung emission from the compression phase of relativistic heavy ion collisions based on a hydrodynamical description of the collision proces…
Thermal photon production in heavy ion collisions
N. Arbex, U. Ornik, M. Plümer +2
Using a three-dimensional hydrodynamic simulation of the collision and an equation of state containing a first order phase transition to the quark-gluon plasma, we study thermal ph…
Hydrodynamical Beam Jets in High Energy Hadronic Collisions
U. Ornik, R. M. Weiner, G. Wilk
A study of hadronic data up to TEVATRON energies in terms of relativistic hydrodynamics indicates an extended 1-dimensional stage of the expansion which suggests a jet like behavio…
