Emerging Theory of Strongly Coupled Quark-Gluon Plasma

Abstract

RHIC data have shown robust collective flows, including recent spectacular ``conical flow'' from quenched jets: that confirms that QGP above the critical line is in a strongly coupled regime. One way to study Non-Abelian classical strongly coupled plasmas is via molecular dynamics, which was recently extended to plasmas with electric and magntic charges. First results on its transport (diffusion and viscosity) are reported. AdS/CFT correspondence is another actively pursuit approach to strong coupling regime: we review new results for heavy quark motion and even complete picture of conical flow, obtained from linearized gravity dual. Recent developments in (non-linearized) gravity aims at reproduction of the whole time-dependent picture of the explosion. We finally compare transport properties obtained from RHIC data to those obtained in MD and AdS/CFT.
