We propose a general approach to freezing out fluctuations in heavy-ion collisions using the principle of maximum entropy. We find the results naturally expressed as a direct relationship between the irreducible relative correlators quantifying the deviations of hydrodynamic as well as hadron gas fluctuations from the ideal hadron gas baseline. The method also allows us to determine heretofore unknown parameters crucial for the freezeout of fluctuations near the QCD critical point in terms of the QCD equation of state.

    nucl-th 2026-07 unverdicted novelty 6.0 of 10

    A viscous Langevin model with lattice-QCD equation-of-state inputs reproduces C_pT centrality scaling at RHIC top energies and flags a 7.7 GeV deviation as possible critical-point physics.

  2. Theoretical Review of Critical Point Predictions

    nucl-th 2026-08 conditional

    A review of QCD critical point theory structured around the maximum entropy freeze-out framework for connecting hydrodynamic fluctuations to proton factorial cumulants, plus the dynamics of critical fluctuations.
