The gauge-gravity duality and heavy ion collisions

Abstract

This chapter provides a review of two particular applications of the gauge-gravity duality to heavy ion collisions. The first involves a study of the wake of a quark as it travels through the quark gluon plasma and its possible connection to measurements of jet correlations carried out at the relativistic heavy ion collider at Brookhaven. The second section provides, via the gauge/gravity duality, a lower bound on the entropy produced in a collision of two energetic distributions. This is then compared to particle multiplicity in gold-gold collisions. © 2011 Springer-Verlag Berlin Heidelberg.
