# Refractive distortions of two-particle correlations from classical trajectory calculations

## Abstract

Calculations of two-particle correlations usually assume that particles interact only pairwise after their final collisions with third bodies. By considering classical trajectories, I show that interactions with the mean field can alter the spatial dimensions of the outgoing phase-space-density profiles, consistent with more complicated quantum complications. We find that if the pion dispersion relation is strongly modified, these distortions can be of the order of 10% or more.
