Thermally Fluctuating Second-Order Viscous Hydrodynamics and Heavy-Ion Collisions

Nuclear Theory 2015-04-16 v1

Abstract

The fluctuation-dissipation theorem requires the presence of thermal noise in viscous fluids. The time and length scales of heavy ion collisions are small enough so that the thermal noise can have a measurable effect on observables. Thermal noise is included in numerical simulations of high energy lead-lead collisions, increasing average values of the momentum eccentricity and contributing to its event by event fluctuations.
