Nuclear Physics & RIKEN Theory Seminar

"Bulk viscosity and the applicability of viscous hydrodynamics at RHIC"

Presented by Pasi Huovinen, University of Frankfurt

Friday, February 26, 2010, 2:00 pm — Small Seminar Room, Bldg. 510

Based on comparisons with transport models we had concluded that relativistic viscous hydrodynamics is quite applicable at RHIC. However, when bulk viscosity is included in the description, the applicability can be severely reduced. In this talk I briefly review the comparisons with kinetic theory, propose as a rule of thumb that the entropy production during the evolution has to stay below 20% for hydrodynamic description to be applicable, and show what limits this gives to bulk viscosity and/or the applicability of hydro with bulk viscosity.
