Abstract

We derive a general formula for the correlation function of two identical particles with the inclusion of multiple elastic scatterings in the medium in which the two particles are produced. This formula involves the propagator of the particle in the medium. As an illustration of the effect we apply the formula to the special case where the scatterers are static, localized two-body potentials. In this illustration both Rside2 and Rout2 are increased by an amount proportional to the square of the spatial density of scatterers and to the differential cross section. Specific numbers are used to show the expected magnitude of the rescattering effect on kaon interferometry.
