Bulk viscosity of gauge theory plasma at strong coupling

High Energy Physics - Theory 2008-11-26 v2

Abstract

We propose a lower bound on bulk viscosity of strongly coupled gauge theory plasmas. Using explicit example of the N=2^* gauge theory plasma we show that the bulk viscosity remains finite at a critical point with a divergent specific heat. We present an estimate for the bulk viscosity of QGP plasma at RHIC.
