System size, energy, pseudorapidity, and centrality dependence of elliptic flow.
This Letter presents measurements of the elliptic flow of charged particles as a function of pseudorapidity and centrality from Cu-Cu collisions at 62.4 and 200 GeV using the PHOBOS detector at the Relativistic Heavy Ion Collider. The elliptic flow in Cu-Cu collisions is found to be significant even for the most central events. For comparison with the Au-Au results, it is found that the detaile...
متن کاملSystem Size and Energy Dependence of Elliptic Flow
The elliptic flow v2 is presented for the Cu+Cu collisions at √ sNN = 62.4 and 200 GeV, as a function of pseudorapidity. Comparison to results for the Au+Au collisions at the same energies shows a reduction of about 20% in the flow observed for a centrality selection of 0-40%. The centrality dependent flow, expressed as a function of the number of participants Npart, is compared for the Cu+Cu a...
متن کاملNuclear profile dependence of elliptic flow from a parton cascade
The transverse profile dependence of elliptic flow is studied in a parton cascade model. We demonstrate that the impact parameter dependence of elliptic flow depends sensitively on the transverse profile of initial particles, however, if elliptic flow is plotted as a function of the relative multiplicity, the nuclear profile dependence disappears. The insensitivity was found previously in a hyd...
متن کاملEnergy and system size dependence of elliptic flow: using rapidity gaps to suppress non-flow contribution
In this talk I present new STAR results on measurements of integrated elliptic flow at midrapidity in Au+Au and Cu+Cu collisions at √ sNN =200 and 62 GeV energies. These results have been obtained from azimuthal correlations between particles in the main STAR TPC and two forward TPCs, and are to a large extent free from so-called non-flow correlations. These results along with the previously re...
متن کاملelliptic flow ? ∗
We can establish a new picture, the perfect fluid strongly coupled quark gluon plasma (sQGP) core and the dissipative hadronic corona, of the space-time evolution of produced matter in relativistic heavy ion collisions at RHIC. It is also shown that the picture works well also in the forward rapidity region through an analysis based on a new class of the hydro-kinetic model and is a manifestati...
