Heisenberg saturation of the Froissart bound from AdS-CFT

TL;DR

This paper demonstrates how high-energy QCD saturation phenomena, specifically the Froissart bound, can be understood through AdS-CFT correspondence, linking gravitational shockwave collisions to pion field dynamics and black hole formation.

Contribution

It provides a physical interpretation of Froissart bound saturation via AdS-CFT, connecting gravitational shockwaves and black hole production to QCD pion field solitons.

Findings

Saturation occurs through black hole production on the IR brane.

The process maps to nonlinear pion field solitons in QCD.

Agreement with Heisenberg's 1952 pion collision description.

Abstract

In a previous paper, we have analyzed high energy QCD from AdS-CFT and proved the saturation of the Froissart bound (a purely QCD proof of which is still lacking). In this paper we describe the calculation in more physical terms and map it to QCD language. We find a remarkable agreement with the 1952 Heisenberg description of the saturation (pre-QCD!) in terms of shockwave collisions of pion field distributions. It provides a direct map between gauge theory physics and the gravitational physics on the IR brane of the Randall-Sundrum model. Saturation occurs through black hole production on the IR brane, which is in QCD production of a nonlinear pion field soliton of a Born-Infeld action in the hadron collision, that decays into free pions.
