Deterministic confluent equations are derived for three-point correlations of non-Gaussian fluctuations in relativistic stochastic hydrodynamics, including fluctuating velocity, using a covariant formalism in the average local Landau frame.
Finite current relaxation introduces memory effects that suppress, shift, and reshape non-monotonic cumulant behavior relative to instantaneous equilibrium and Fickian diffusion, most visibly in higher-order cumulants.
Local baryon conservation in a canonical ensemble drives net-proton κ6/κ2 to small or negative values in restricted acceptance, establishing a baseline that must be subtracted before interpreting signals of chiral criticality.
In Bjorken flow, non-Gaussian velocity fluctuations evolve with nonlinear coupling between two- and three-point correlators and memory effects, best analyzed in the average Landau frame which coincides with the density frame.
