A Gravity Dual of RHIC Collisions

arXiv:hep-th/0511199 · doi:10.3938/jkps.50.384

Abstract

In the context of the AdS/CFT correspondence we discuss the gravity dual of a heavy-ion-like collision in a variant of SYM. We provide a gravity dual picture of the entire process using a model where the scattering process creates initially a holographic shower in bulk AdS. The subsequent gravitational fall leads to a moving black hole that is gravity dual to the expanding and cooling heavy-ion fireball. The front of the fireball cools at the rate of , while the core cools as from a cosmological-like argument. The cooling is faster than Bjorken cooling. The fireball freezes when the dual black hole background is replaced by a confining background through the Hawking-Page transition.
