Findings

Non-local correlations scale with transport coefficients.

Hydrodynamic signatures can be identified in short-range correlation measurements.

The approach links microscopic scattering dynamics to macroscopic correlation patterns.

Abstract

We investigate hydrodynamic contributions to short-range two-particle correlations in relativistic heavy-ion collisions using the Boltzmann-Langevin equation. We derive and solve the transport equation for equal-time two-point correlations, obtaining both local and non-local contributions that scale with transport coefficients. The non-local correlations emerging from 2-to-2 scattering dynamics provide a hydrodynamic signature in short-range correlation measurements.
