338. Heavy Ion Physics After Nine Years of RHIC Operation

Brian Cole (Physics Dept., Pupin Physics Lab.-Columbia University-Unknown)

Heavy Ion Physics/Hot and Dense QCD

The Relativistic Heavy Ion Collider at Brookhaven National Laboratory was designed to explore the confinement to de-confinement transition in QCD at high temperatures and low baryon densities. Results from the RHIC program have provided overwhelming circumstantial evidence for the formation of quark gluon plasma in nuclear collisions at RHIC. Estimates obtained from several different RHIC...

245. Equation of State and the finite temperature transition for hot QCD

Heavy Ion Physics/Hot and Dense QCD

This talk will summarize the results obtained by the HotQCD collaboration on the equation of state and the crossover transition in 2+1 flavor QCD. We will present results on bulk thermodynamic quantities - energy density, pressure, entropy density, and the speed of sound over the temperature range 140 < T < 540 MeV. These results have been obtained on lattices of temporal size $N_\tau = 6$...

361. Anisotropic collective phenomena in ultra-relativistic nuclear collisions

Heavy Ion Physics/Hot and Dense QCD

Recent developments in the field of anisotropic flow, measurements and interpretations, are reviewed with an emphasis on relation to the bulk properties of the medium.

357. Test of the viscous hydrodynamic paradigm for RHIC

Heavy Ion Physics/Hot and Dense QCD

The past couple years have seen a lot of progress in the application of causal dissipative hydrodynamics to model heavy-ion collisions at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory. These advances benefited greatly from breakthrough results obtained in the gravity (AdS/CFT) dual of theories based on N=4 supersymmetric Yang-Mills. 2+1D viscous...

168. Viscous Evolution of a Quark Gluon Plasma

Heavy Ion Physics/Hot and Dense QCD

This work investigates the consequence of the non-equilibrium phase space distribution on elliptic flow and particle spectra using a viscous hydrodynamic simulation. First, we show how various models of energy loss lead to different viscous corrections to spectra and make a connection between the shear viscosity coefficient and the transport parameter q-hat. The off-equilibrium distribution...

36. Viscous hydrodynamics with shear and bulk viscosity for Relativistic Heavy Ion Collisions

Heavy Ion Physics/Hot and Dense QCD

The viscosity of the QGP is a presently hotly debated subject. Since its computation from first principles is difficult, it is desirable to try to extract it from experimental data. Viscous hydrodynamics provides a tool that can attack this problem and which may work in regions where ideal hydrodynamics begins to fail.\\ Through the efforts of different groups, the elliptic flow has...
