A non-fluctuational signature of the QCD critical point

We propose a novel, non-fluctuational signature of the QCD critical point, originating from hydrodynamic trajectories that bend toward the maximum of the specific entropy per baryon along the chiral phase transition boundary. Specifically, if the critical point lies sufficiently close to the freeze-out points, the freeze-out chemical potential may exhibit a discontinuous jump as a function of the collision energy.
