Description
Fluctuations play crucial role in determining properties of the QCD equation of state and transport in heavy-ion collision experiments. Recent progress in understanding evolution of fluctuations in relativistic hydrodynamics aims at providing predictive description of the fluctuations, including their non-gaussianity. The problem of connecting the predictions of hydrodynamics with experimental measurements of fluctuations requires a description of freeze-out which, similar to hydrodynamics itself, fulfills conservation laws on event-by-event basis. The maximum entropy approach elegantly solves this long-standing problem.
