Many--particle correlations due to Bose-Einstein interference are studied in ultrarelativistic heavy--ion collisions. We calculate the higher order correlation functions from the 2--particle correlation function by assuming that the source…
We present a model to describe the emission of two protons in electron scattering experiments. The process is induced by one-body electromagnetic operators acting together with short-range correlations, and by two-body Delta currents. The…
