The RHIC fireball as a dual black hole

Abstract

We argue that the fireball observed at RHIC is (the analog of) a dual black hole. In previous works, we have argued that the large ss behaviour of the total QCD cross section is due to production of dual black holes, and that in the QCD effective field theory it corresponds to a nonlinear soliton of the pion field. Now we argue that the RHIC fireball is this soliton. We calculate the soliton (black hole) temperature, and get T=4a<mπ>/πT=4a <m_{\pi}>/\pi, with aa a nonperturbative constant. For a=1a=1, we get 175.76MeV175.76 MeV, compared to the experimental value of the fireball ``freeze-out'' of about 176MeV176 MeV. The observed η/s\eta/ s for the fireball is close to the dual value of 1/4π1/4\pi. The ``Color Glass Condensate'' (CGC) state at the core of the fireball is the pion field soliton, dual to the interior of the black hole. The main interaction between particles in the CGC is a Coulomb potential, due to short range pion exchange, dual to gravitational interaction inside the black hole, deconfining quarks and gluons. Thus RHIC is in a certain sense a string theory testing machine, analyzing the formation and decay of dual black holes, and giving information about the black hole interior.
