Mass Effects in Bose Einstein Correlations

Abstract
Bose-Einstein symmetrization can lead to correlations between out going identical particles which reflect the space-time extent of the collision process. At LEP and LEPII these correlations have been studied as a function of a single variable Q, the invariant momentum separation. Assuming a simple form for the correlation function the experiments find source radii dependent on the hadron mass. In this note, I point out that such effects can arise from purely kinematic considerations, although these are unlikely to explain the observed effects completely.
