The Effects of Bose-Condensates on Single Inclusive Spectra and Bose-Einstein Correlations
U. Ornik, M. Plümer, B. R. Schlei +2
The implications of the formation of a Bose condensate on one- and two-particle spectra are studied for ultrarelativistic nucleus-nucleus collisions in the framework of a hydrodyna…
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…
Hydrodynamic Evolution of Chirally Symmetric Nuclear Matter
F. Navarra, U. Ornik
The equation of state of the linear sigma model in the mean field approximation is used as input in a relativistic hydrodynamical numerical routine. Longitudinal and transverse ene…
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…
On the Role of Dissipation in the Early Stages of Relativistic Heavy Ion Collisions
L. Mornas, U. Ornik
The influence of the dissipative terms on the conditions of formation and the characteristic parameters of shock waves in relativistic nuclear collisions is investigated for three…
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…
