“Viscosity of the primordial matter produced in heavy-ion collisions”
In 2005, Brookhaven National Laboratory issued a press release claiming that RHIC scientists have created a perfect fluid having an extremely low viscosity. The viscosity of the matter produced in relativistic heavy ion collisions cannot be measured directly but is instead inferred from a careful consideration of observed flow patterns. In the first part of this talk I will give a basic introduction to the phenomenon of hydrodynamic flow in heavy-ion collisions followed by an overview of the modeling of heavy-ion collisions with viscous hydrodynamics and kinetic theory. In the second part of this talk, I will consider how bulk and shear viscosity affect various flow observables in several simplified models and the current prospects for placing bounds on these transport coefficients. Bounds on the bulk viscosity may have implications for precision cosmology.
*Refreshments will be served at 2:30 pm in SES 2214*
