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