Abstract

We discuss Bose-Einstein correlation functions and momentum distributions which describe boson-emitting systems containing a central part surrounded by a large halo. If the characteristic size of the halo is sufficiently large, the contributions of central part and the halo to the invariant momentum distribution are shown to be separable. The momentum-dependence of the intercept parameter of the correlation functionplays a central role. Almost all high energy reactions including lepton-lepton, lepton hadron, hadron-hadron and nuclear reactions are interpretable as boson emitting systems with large halo. The results are applied to high energy heavy ion data taken at CERN SPS. New insights are obtained for the description of low transverse momentum enhancementof pions.
