Abstract

En 中文
Bose-Einstein correlations in relativistic heavy ion collisions are very different for opaque sources than for transparent ones. The Bose-Einstein radius parameters measured in two-particle correlation functions depend sensitively on the mean free path of the particles. In particular we find that the outward radius parameter for an opaque source is smaller than the sideward radius parameter for sufficiently short duration of emission. A long duration of emission can compensate the opacity reduction of the longitudinal radius parameter and explain the experimental measurements of very similar side-and outward radius parameters.
