Applicability of viscous hydrodynamics at RHIC
arXiv:0907.5014 · doi:10.1016/j.nuclphysa.2009.10.104
Abstract
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.
