After combining into hadrons, these conservation laws manifest themselves as measurable correlations that are sensitive to when charges are created, and how they diffuse apart from one another. This work describes a full simulation of the evolving correlations superimposed on a state-of-the-art microscopic description of the relativistic heavy-ion collision. The results largely describe preliminary experimental results and suggest that the early matter in those collisions comes close to maintaining chemical equilibrium.
