Bose-Einstein Correlations for Longitudinally Expanding Finite Systems

Abstract

Bose-Einstein correlations and momentum distributions are calculated for longitudinally expanding systems, like jets or high energy heavy ion collisions with light projectiles. The expansion generates a thermal length-scale in the longitudinal direction, and the geometrical length-scale is also finite. The Bose-Einstein correlation functions are dominated by the smaller while the invariant momentum distribution by the longer of the two longitudinal length-scales.
