More on the RHIC fireball and dual black holes

We revisit the issue of the RHIC “fireball” as a dual black hole, and explain some of the details. We discuss the nature of the (black hole) information paradox as a purely field theory (gauge theory) phenomenon and how the paradox can be formulated in exactly the same way for the RHIC fireball and a black hole. We stress the differences between the black holes produced in the gravity dual and the equilibrium situation of the Witten construction for finite temperature AdS-CFT. We analyze the thermodynamics of the fireball, give more arguments why Tfireball ∝ mπ, including an effective field theory one, and explain what entropy=area/4 means experimentally for the fireball.
