57. The QGP shear viscosity: elusive goal or just around the corner?

Chun Shen (Ohio State University), Ulrich Heinz (The Ohio State University)

Global and collective dynamics

Parallel

The last two years have seen tremendous progress in the theoretical tools for extracting the specific shear viscosity of the quark-gluon plasma in the temperature range explored by heavy-ion collisions at RHIC and LHC. The effects of viscosity on the transverse momentum spectra and differential elliptic flow and their interplay with other hydrodynamic parameters have been studied...

439. Charged hadron azimuthal anisotropy (v_2) in $sqrt s_{NN} = 2.76 $ TeV PbPb collisions from CMS

Global and collective dynamics

Parallel

During the past decade, azimuthal correlation measurements have played a pivotal role in our understanding of the properties of high density QCD matter through their sensitivity to the early stage evolution of relativistic heavy-ion collisions. Despite our increased understanding of the transport coefficients of the plasma produced in these collisions, there remain many questions concerning...

581. Elliptic and triangular flow of identified particles measured with the ALICE detector.

Global and collective dynamics

Parallel

The anisotropic flow of identified particles is an important observable to test the collective behavior of the matter created in heavy-ion collisions. We report on the first measurements of elliptic and triangular flow for charged pions, kaons and protons in lead-lead collisions at 2.76 TeV per nucleon pair center of mass energy, measured with the ALICE detector at the LHC. We will make a...

526. PHENIX measurements of higher-order flow harmonics in Au+Au collisions at $\sqrt{s_{NN}}=200$ GeV: implications for Initial-eccentricity models and the specific viscosity of the Quark Gluon Plasma

Global and collective dynamics

Parallel

The higher-order flow harmonics $v_n$ can provide constraints crucial for precision extraction of the specific shear viscosity eta/s, of the plasma (QGP) produced in full energy ($\sqrt{s_{NN}}=200$ GeV) Au+Au collisions at RHIC. It can also provide reliable estimates of the flow correlations which contribute to the underlying event for jet-driven two-particle azimuthal angle correlation...

253. Event anisotropy $v_{2}$ of identified hadrons and light nuclei in Au+Au collisions at $\sqrt{s_{NN}}=$ 7.7, 11.5 and 39 GeV with STAR

QCD phase diagram

Parallel

The main goal of the RHIC Beam Energy Scan (BES) is the exploration of the QCD phase diagram in the region of a possible phase transition between the Quark Gluon Plasma (QGP) and the hadron gas phase. In the year 2010 the first part of the BES program was successfully accomplished by recording data from Au+Au collisions at $\sqrt{s_{NN}}=$ 7.7, 11.5 and 39 GeV. The second harmonic...

310. Sensitivity of the elliptic flow coefficient to a temperature-dependent shear viscosity-to-entropy density ratio in ultrarelativistic heavy-ion collisions at RHIC and LHC

Dr Harri Niemi (Frankfurt Institute for Advanced Studies)

Global and collective dynamics

Parallel

We investigate the effects of a temperature-dependent shear viscosity-to-entropy density ratio $\eta/s$ on the elliptic flow of hadrons in ultrarelativistic heavy-ion collisions [1]. We use relativistic dissipative fluid dynamics to model the space-time evolution of the hot and dense system formed in such collisions. The final hadron spectra are calculated using the Cooper-Frye...
