Energy and system size dependence of elliptic flow: using rapidity gaps to suppress non-flow contribution
نویسنده
چکیده
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 reported values of “participant” eccentricity taking into account eccentricity fluctuations are used for testing the v2/ε scaling, which is found to hold relatively well.

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 کاملFlow systematics from SIS to SPS energies
The various flow phenomena observed at energies between 50 AMeV and 160 AGeV are reviewed. I first define three types of flow: directed flow and elliptic flow, which are the two first Fourier components of the azimuthal distribution in non-central collisions; radial flow, which is deduced from an analysis of transverse momentum spectra in central collisions. Then, I review the observations of d...
متن کاملToward the energy and the system size dependence of ellip- tic flow: working on flow fluctuations
In this talk I concentrate on two topics closely related to the understanding of the energy and the system size dependence of the elliptic flow: determination of the elliptic flow (v2) “free” from the effects of non-flow and flow fluctuations, and the role of fluctuations in the initial eccentricity of the overlap region. I introduce a new approach for the analysis of the distribution in flow v...
متن کاملUnderstanding the rapidity dependence of the elliptic flow and the HBT radii at RHIC
The pseudo-rapidity dependence of the elliptic flow at various excitation energies measured by the PHOBOS Collaboration in Au+Au collisions at RHIC is one of the surprising results that has not been explained before in terms of hydrodynamical models. Here we show that these data are in agreement with theoretical predictions and satisfy the universal scaling relation predicted by the Buda-Lund h...
متن کاملNumerical Simulation of Separation Bubble on Elliptic Cylinders Using Three-equation k-? Turbulence Model
Occurrence of laminar separation bubbles on solid walls of an elliptic cylinder has been simulated using a recently developed transitional model for boundary layer flows. Computational method is based on the solution of the Reynolds averaged Navier-Stokes (RANS) equations and the eddy-viscosity concept. Transitional model tries to simulate streamwise fluctuations, induced by freestream turbulen...
