Bose-Einstein Correlations as correlations of fluctuations

Abstract

The limitations of the recently proposed new method of numerical modelling of Bose-Einstein correlations (BEC) are explicitly demonstrated. It is then argued that BEC should still be considered as emerging from the correlations of fluctuations, however they have to be modelled first in any Monte Carlo event generator (MCEG) and not added {\it a posteriori} to the existing output of some MCEG.
