Collective flow without hydrodynamics: simulation results for relativistic ion collisions

Relativistic hydrodynamics for heavy-ion collisions

Relativistic hydrodynamics is essential to our current understanding of nucleus-nucleus collisions at ultrarelativistic energies (current experiments at the Relativistic Heavy Ion Collider, forthcoming experiments at the CERN Large Hadron Collider). This is an introduction to relativistic hydrodynamics for graduate students. It includes a detailed derivation of the equations, and a description ...

Hydrodynamics and collective behaviour in relativistic nuclear collisions

Hydrodynamics is applied to describe the dynamics of relativistic heavy-ion collisions. The focus of the present study is the influence of a possible (phase) transition to the quark–gluon plasma in the nuclear matter equation of state on collective observables, such as the lifetime of the system and the transverse directed flow of matter. It is shown that such a transition leads to a softening ...

Collective dynamics in highly relativistic heavy-ion collisions∗

A. Dumitru Physics Department, Yale University P.O. Box 208124, New Haven, CT 06520, USA D.H. Rischke RIKEN-BNL Research Center, Brookhaven National Laboratory Upton, NY 11973, USA (September 17, 1998) We calculate the transverse momentum spectra of various hadrons and clusters (π, K, N , Φ, Λ, Ω, d, ΛΛ, He) in central Au+Au at √ s = 200A GeV (RHIC energy) up to pT = 4 GeV within hydrodynamics....

Thermal Freeze-out and Longitudinally Non-uniform Collective Expansion Flow in Relativistic Heavy Ion Collisions

The non-uniform longitudinal flow model (NUFM) propsed recently is extended to include also transverse flow. The resulting longitudinally nonuniform collective expansion model (NUCEM) is applied to the calculation of rapidity distribution of kaons, lambdas and protons in relativistic heavy ion collisions at CERN-SPS energies. The model results are compared with the 200 A GeV/c S-S and 158 A GeV...
