Rapidity and system size dependence of anisotropic flows in relativistic heavy ion collisions
The azimuthal anisotropy of hadron transverse momentum distributions in heavy ion collisions at RHIC is sensitive to the properties of produced matter. In the framework of transport approach, it was shown in Ref.[ 1] using the ZPC model [ 2] that the value of the second harmonic, i.e., the elliptic flow, depends sensitively on the magnitude of parton scattering cross sections. With a more reali...
متن کاملPseudorapidity dependence of parton energy loss in relativistic heavy ion collisions
We analyze the recent data from the BRAHMS Collaboration on the pseudorapidity dependence of nuclear modification factors in Au+Au collisions at √ sNN = 200 GeV by using the full three dimensional hydrodynamic simulations for the density effects on parton energy loss. We first compute the transverse spectra at η = 0 and 2.2, and next take a ratio Rη = RAA(η = 2.2)/RAA(η = 0), where RAA is a nuc...
متن کاملMicroscopic description of anisotropic flow in relativistic heavy ion collisions
Abstract. Anisotropic flow of hadrons is studied in heavy ion collisions at SPS and RHIC energies within the microscopic quark-gluon string model. The model was found to reproduce correctly many of the flow features, e.g., the wiggle structure of direct flow of nucleons at midrapidity, or centrality, rapidity, and transverse momentum dependences of elliptic flow. Further predictions are made. T...
متن کاملScaling of Anisotropic Flows in Intermediate Energy and Ultra-relativistic Heavy Ion Collisions
Anisotropic flows (v2 and v4) of hadrons and light nuclear clusters are studied by a partonic transport model and nucleonic transport model, respectively, in ultra-relativistic and intermediate energy heavy ion collisions. Both number-of-constituent-quark scaling of hadrons, especially for φ meson which is composed of strange quarks, and number-of-nucleon scaling of light nuclear clusters are d...
متن کاملAnisotropic flow in ultra-relativistic heavy ion collisions
A sign reversal of the directed flow parameter v1 in the central rapidity region in Au+Au collisions at √ s = 200 AGeV is predicted. This anti-flow is shown to be linked to the expansion of the hot matter created. In line with this observation the predicted elliptic flow parameter v2 of various particle species is linked to the mean free path of these particles. LBNL-preprint: LBNL-46096 Typese...
