551. Shocks in Quark-Gluon Plasma

Edward Shuryak (stony brook university)

Oral Presentation

Large energy deposition from LHC quenching jets restarted interest to shock formation. Shocks also have theoretical significance as the simplest out-of-equilibrium setting without time dependence. While weak shocks have small gradients and can be treated hydrodynamically in the Navier-Stokes (NS) approximation, the ones without a small parameter (strong shocks) needs other methods. Two...

328. PHENIX Measurements of Higher-order Flow Harmonics for Identified Charged Hadrons in Au+Au Collisions at 39 – 200 GeV

Oral Presentation

Collective flow measurements continue to play an important role in ongoing efforts to map out the temperature dependence of the transport coefficient $\frac{\eta}{s}(T)$, for the strongly interacting matter produced in heavy ion collisions at RHIC. Recently, PHENIX has performed a detailed set of measurements of the higher-order flow coefficients ($v_{n}$ for n=2,3,4), for both inclusive and...

156. Beam Energy Dependence of First and Higher-Order Flow Harmonics from the STAR Experiment at RHIC

Yadav Pandit (Kent State University)

Global and collective dynamics

Oral Presentation

A primary goal of the RHIC Beam Energy Scan (BES) is to search for evidence of a transition between a hadron gas and a Quark Gluon Plasma. The dependence of $v_{1}$ and higher flow harmonics on system size and beam energy may be sensitive to the degrees of freedom in the system, as a consequence of early pressure gradients and a potential softening in the equation of state. In this talk,...

32. Collision Energy Dependence of Viscous Hydrodynamic Flow in Relativistic Heavy-Ion Collisions

Chun Shen (Ohio State University)

Global and collective dynamics

Oral Presentation

We present a systematic study on the evolution of hadron spectra and their azimuthal anisotropy from the lowest collision energy studied at the Relativistic Heavy Ion Collider (RHIC), √s = 7.7A GeV, to the highest energy reachable at the Large Hadron Collider (LHC), √s = 5500A GeV [1]. As the collision energy increases, the resulting increases of the initial temperature, and fireball lifetime,...

521. Non-linear anisotropic flow with ideal and viscous hydrodynamics

Mr Li Yan (Stony Brook University)

14/08/2012, 15:35

Oral Presentation

The particle spectrum from RHIC and LHC can be decomposed into harmonic series that defines the dipolar flow $v_1$, the elliptic flow $v_2$, the triangular flow $v_3$, and $v_4$, and $v_5$ etc. To understand the origin of higher order harmonics, we extend the linear response formalism for anisotropic flow to include the non-linear response which results from the interactions between the lowest...

79. Derivation of transient relativistic fluid dynamics from the Boltzmann equation for a multi-component system

Gabriel Denicol (Frankfurt University)

14/08/2012, 15:55

Global and collective dynamics

Oral Presentation

We present a general derivation of relativistic fluid dynamics from the relativistic Boltzmann equation using the method of moments [1]. The main difference between our approach and the traditional 14-moment approximation is that we do not close the fluid-dynamical equations of motion by truncating the expansion of the single-particle momentum distribution function. Instead, we keep all the...
