Description
The search for the QCD critical point in heavy-ion collision experiments requires dynamical modeling of the bulk evolution of the QCD matter as well as of the fluctuations near the critical point. We develop a general formalism which couples hydrodynamics of a relativistic fluid to critical fluctuations. The resulting “Hydro+” theory extends hydrodynamics into the regime where the critical slowing down would otherwise make hydrodynamics inapplicable. At the same time, Hydro+ also describes non-trivial off-equilibrium effects on the critical fluctuations, allowing to simulate the coupled evolution of the bulk hydrodynamic modes and the critical fluctuations in one framework. As an illustration, we consider a simple Bjorken-like model of heavy-ion collisions near the critical point.
