#### Abstract

I analyze the high energy collisions of hadrons in QCD from the point of view of gravity duals of QCD. Dual black hole formation dominates at least above 10 GeV, and the total QCD cross section behaviour with s is obtained. The saturation of the Froissart bound in QCD maps to production of black holes in the IR of the dual. These correspond to the RHIC fireballs and similar objects expected at the LHC. The temperature of the fireball is derived, as well as other properties. A simple field theory toy model shows how it is possible to obtain black hole-like properties in QFT. The model has thermal horizons that trap information, and presents aparent information loss, which should be restored by unitarity.
