  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.
