Title: Elliptic Flow at Large Viscosity

Abstract

Here, in this contribution we present an alternative scenario for the large elliptic flow observed in relativistic heavy ion collisions. Motivated by recent results from Lattice QCD on flavor off-diagonal susceptibilities we argue that the matter right above T_c can be described by single-particle dynamics in a repulsive single-particle potential, which in turn gives rise to elliptic flow. Lastly, these ideas can be tested experimentally by measuring elliptic flow of heavy quarks, preferably via the measurement of J/Ψ elliptic flow.

Elliptic Flow and Single Particle Dynamics

Journal Article Koch, Volker - AIP Conference Proceedings

In this contribution we present an alternative scenario for the large elliptic flow observed in relativistic heavy ion collisions. Motivated by recent results from Lattice QCD on flavor off-diagonal susceptibilities we argue that the matter right above T{sub c} can be described by single-particle dynamics in a repulsive single-particle potential, which in turn gives rise to elliptic flow. These ideas can be tested experimentally by measuring elliptic flow of heavy quarks, preferably via the measurement of J/{psi} elliptic flow.

Elliptic flow splittings in the Polyakov–Nambu–Jona-Lasinio transport model

Journal Article Zhou, Wen-Hao ; Liu, He ; Li, Feng ; ... - Physical Review. C

To incorporate the effect of gluons on the evolution dynamics of the quark matter produced in relativistic heavy-ion collisions, we extend the three-flavor Nambu–Jona-Lasinio (NJL) transport model to include the contribution from the Polyakov loops. Imbedding the resulting pNJL partonic transport model in an extended multiphase transport (extended AMPT) model, we then study the elliptic flow splittings between particles and their antiparticles in relativistic heavy-ion collisions at beam energy scan energies. We find that a weak quark vector interaction in the partonic phase is able to describe the elliptic flow splitting between protons and antiprotons in heavy-ion collisions at √sNN=7.7more »« less

Centrality dependence of elliptic flow, the hydrodynamic limit, and the viscosity of hot QCD

Journal Article Drescher, Hans-Joachim ; Dumitru, Adrian ; Gombeaud, Clement ; ... - Physical Review. C, Nuclear Physics

We show that the centrality and system-size dependence of elliptic flow measured at the BNL Relativistic Heavy Ion Collider (RHIC) are fully described by a simple model based on eccentricity scaling and incomplete thermalization. We argue that the elliptic flow is at least 25% below the (ideal) ''hydrodynamic limit,'' even for the most central Au-Au collisions. This lack of perfect equilibration allows for estimates of the effective parton cross section in the quark-gluon plasma and of its viscosity to entropy density ratio. We also show how the initial conditions affect the transport coefficients and thermodynamic quantities extracted from the data,more »« less

Breaking of the number-of-constituent-quark scaling for identified-particle elliptic flow as a signal of phase change in low-energy data taken at the BNL Relativistic Heavy Ion Collider (RHIC)

Journal Article Tian, J ; Jin, F ; Zhang, S ; ... - Physical Review. C, Nuclear Physics

We argue that measurements of identified-particle elliptic flow in a wide energy range could shed light on the possible phase change in high-energy heavy ion collisions at the BNL Relativistic Heavy Ion Collider (RHIC). When the hadronization process is dominated by quark coalescence, the number-of-constituent-quark (NCQ) scaling for the identified-particle elliptic flow can serve as a probe for studying the strong interacting partonic matter. In the upcoming RHIC low-energy runs, the NCQ scaling behavior may be broken because of the change of the effective degrees of freedom of the hot dense matter, which corresponds to the transition from the dominantmore »« less
