Anisotropic transverse flow and the quark-hadron phase transition
Peter F. Kolb, Josef Sollfrank, Ulrich Heinz
We use (3+1)-dimensional hydrodynamics with exact longitudinal boost-invariance to study the influence of collision centrality and initial energy density on the transverse flow pat…
Hydrodynamic simulation of elliptic flow
P. F. Kolb, J. Sollfrank, P. V. Ruuskanen +1
We use a hydrodynamic model to study the space-time evolution transverse to the beam direction in ultrarelativistic heavy-ion collisions with nonzero impact parameters. We focus on…
Anisotropic flow from AGS to LHC energies
Peter F. Kolb, Josef Sollfrank, Ulrich Heinz
Within hydrodynamics we study the effects of the initial spatial anisotropy in non-central heavy-ion collisions on the momentum distributions of the emitted hadrons. We show that t…
Kinetic Freeze-out and Radial Flow in 11.6 A GeV Au+Au Collisions
Harald Dobler, Josef Sollfrank, Ulrich Heinz
We study the kinetic freeze-out conditions of hadrons in Au+Au collisions at 11.6 A GeV/c using different parametrizations of an expanding thermal fireball. We take into account th…
On local and global equilibrium in heavy ion collisions
J. Sollfrank
The thermal model is commonly used in two different ways for the description of hadron production in ultra-relativistic heavy ion collision. One is the application of the thermal m…
Thermal analysis of hadron multiplicities from relativistic quantum molecular dynamics
J. Sollfrank, U. Heinz, H. Sorge +1
Some questions arising in the application of the thermal model to hadron production in heavy ion collisions are studied. We do so by applying the thermal model of hadron production…
