# Energy-momentum tensor correlators and viscosity

@inproceedings{Meyer2008EnergymomentumTC, title={Energy-momentum tensor correlators and viscosity}, author={Harvey B. Meyer}, year={2008} }

Collective flow has been observed in heavy ion collisions, with a large anisotropic component, and ideal hydrodynamic calculations had significant successful in describing the distribution of produced particles at the RHIC experiments. In order to account for this near ideal fluid behavior, the shear and bulk viscosity of the quark gluon plasma (QGP) must be computed from first principles in a regime where the QGP is not weakly coupled. In this talk I describe recent progress in computing…

Flow at the SPS and RHIC as a quark-gluon plasma signature.

- PhysicsPhysical review letters
- 2001

With the EOS fixed from SPS data, predictions at RHIC are quantified where the quark-gluon plasma (QGP) pressure is expected to drive additional radial and elliptic flows and the strong elliptic flow observed in the first RHIC measurements does not conclusively signal this nascent QGP pressure.

Viscosity information from relativistic nuclear collisions: how perfect is the fluid observed at RHIC?

Relativistic viscous hydrodynamic fits to Brookhaven Rel ativistic Heavy Ion Collider data on the centrality dependence of multiplicity, transverse, and elliptic flow for square root s = 200 GeV Au+Au collisions seem to favor a much smaller viscosity over entropy ratio, below the bound from the anti-de Sitter conformal field theory conjecture.
