摘要：

We present new simulation results on a hard-sphere system at high densities. Using three-time correlations, we can account for the anomalous diffusion, which results from a homogeneous back-dragging effect. Furthermore, we calculate the non-Gaussian parameter and connect it to the existence of dynamic heterogeneities.
