1 AdS-CFT and the RHIC fireball

By Horatiu Nastase

Abstract

In this talk I will review my work on the description of high energy scattering in QCD, in particular the fireball observed at RHIC, as well as predictions for the LHC. The aim is to see how much we can learn about actual QCD (nonsupersymmetric, Nc = 3), without knowing the details of the gravity dual of QCD. Experimental predictions are consistent with data, and important consequences are obtained for the LHC, in particular for the pp collisions. The RHIC and LHC correspond to the regime of Froissart bound saturation, in the Heisenberg model. Asymptotically, the RHIC fireball is mapped to a dual black hole in the IR of the dual. A simple (and unique) scalar field theory model for the RHIC fireball indeed exhibits the properties of the dual black hole: a thermal horizon and aparent information loss. It was hoped since the begining of AdS-CFT with Maldacena’s paper, 1) that eventually we should be able to use the AdS-CFT correspondence to make real predictions about QCD, that can be experimentally tested, and in so doing have indirect experimental tests of string theory. Indirect since we would not be testin
