B. Buschbeck et Hc. Eggers, Multiplicity dependence of Bose-Einstein correlations in (p)over-barp reactions: a discussion of possible origins, NUCL PH B-P, 92, 2001, pp. 235-246
The observed pronounced multiplicity dependence of correlation functions in
hadron-hadron reactions and in particular of Bose-Einstein correlations pr
ovides information about underlying physics. We discuss in this contributio
n several interpretations, giving special attention to the string model for
Bose-Einstein correlations of Andersson and Hofmann, as well as the core-h
alo picture of Csorgo, Lorstad and Zimanyi.
