Thomas Schaefer (NCSU) Stochastic Fluid Dynamics and Fluctuations in Relativistic Heavy Ion Collisions The search for a critical point in the phase diagram of QCD has motivated an experimental effort to study fluctuation observables in relativistic heavy ion physics, and a theoretical effort to develop tools based on stochastic fluid dynamics. We report on recent progress in constricting effective actions for stochastic fluid dynamics, and in performing real time simulations of stochastic fluids.
