To understand the dynamics of cluster formation, starting from homogeneous distribution, we set up classical molecular dynamics simulation of the baryon motion, supplemented by a Langevin equation to model the effect of a meson heat bath. Quantum mechanical kinetic energy is included via an effective potential, tuned to reproduce known properties of nuclear matter. We then modify the inter-nucleon potential, in a way expected in the vicinity of the hypothetical QCD critical point, and calculate the rate of baryon cluster formation. Then we compare it with the time available in real heavy-ion collisions.
