Abstract: We calculate the two-pion correlation function for an expanding hadron source with a finite baryon density. The space–time evolution of the source is described by relativistic hydrodynamics and the Hanbury–Brown–Twiss (HBT) radius is extracted after effects of collective expansion and multiple scattering on the HBT interferometry have been taken into account, using quantum probability amplitudes in a path-integral formalism. We find that this radius is substantially smaller than the HBT radius extracted from the freeze-out configuration.
