AdS-CFT and the RHIC fireball

TL;DR

This paper explores the connection between high energy QCD scattering phenomena, like the RHIC fireball, and their dual descriptions in gravity theories, providing predictions for LHC and insights into the QCD-gravity duality.

Contribution

It demonstrates how the RHIC fireball can be modeled as a dual black hole in a gravity theory, offering a novel perspective on QCD phenomena without detailed gravity duals.

Findings

Experimental predictions align with RHIC and LHC data.

The RHIC fireball corresponds to a dual black hole in the IR of the gravity dual.

A scalar field model reproduces key properties of the dual black hole.

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, $N_c=3$), 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.
