We conjecture that, because of color confinement, the physical vacuum forms an event horizon for quarks and gluons, which can be crossed only by quantum tunneling, i.e., through the QCD counterpart of Hawking radiation at black holes. Since such radiation cannot transmit information to the outside, it must be thermal, of a temperature determined by the chromodynamic force at the confinement surface, and it must maintain color neutrality. We explore the possibility that the resulting process provides a common mechanism for thermal hadron production in high energy interactions, from e+e- annihilation to heavy ion collisions.

On the collision of two shock waves in AdS5 (2008, background): “Thus the problem of thermalization in strongly coupled gauge theories becomes related to the problem of black hole formation, which has been noted before [13] (see also [14,15] for a different proposal on thermalization involving black holes).”
