  Correlations born before the onset of hydrodynamic flow can leave observable
traces on the final state particles. Measurement of these correlations can
yield important information on the isotropization and thermalization process.
Starting from a Boltzmann-like kinetic theory in the presence of dynamic
Langevin noise, we derive a new partial differential equation for the
two-particle correlation function that respects the microscopic conservation
laws. We illustrate how this equation can be used to study the effect of
thermalization on long range correlations.
