Applicability of viscous hydrodynamics at RHIC

Denes Molnar, Pasi Huovinen

Published 2009-07-28, updated 2009-09-29Version 2

In an earlier work (arXiv:0808.0953) we established that causal Israel-Stewart viscous hydrodynamics is only accurate in RHIC applications at very low shear viscosities 4 pi eta_s / s < ~ 1.5-2. We show here that the region of applicability is significantly reduced if bulk viscosity plays a role in the dynamics.
