# DBI scalar field theory for QGP hydrodynamics

@article{Nastase2015DBISF, title={DBI scalar field theory for QGP hydrodynamics}, author={Horatiu Nastase}, journal={Physical Review D}, year={2015}, volume={94}, pages={025014} }

A way to describe the hydrodynamics of the quark-gluon plasma using a Dirac-Born-Infeld (DBI) action is proposed, based on the model found by Heisenberg for high energy scattering of nucleons. The expanding plasma is described as a shockwave in a DBI model for a real scalar standing in for the pion, and I show that one obtains a fluid description in terms of a relativistic fluid that near the shock is approximately ideal ($\ensuremath{\eta}\ensuremath{\simeq}0$) and conformal. One can introduce…

This paper shows that an action can be constructed from the scalar on the horizon which can give the same energy-momentum tensor for the membrane, which is to say, the membrane can be described eﬀectively by the scalars on it.

Using the anti-de Sitter/conformal field theory correspondence, the shear viscosity eta of the finite-temperature N = 4 supersymmetric Yang-Mills theory is related with the absorption cross section of low-energy gravitons by a near-extremal black three-brane and it is shown that in the limit of zero frequency this cross section coincides with the area of the horizon.

We argue that the fireball observed at RHIC is (the analog of) a dual black hole. In previous works, we have argued that the large $s$ behaviour of the total QCD cross section is due to production of…

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.
