Parametrization of Bose-Einstein Correlations and Reconstruction of the   Source Function in Hadronic Z-boson Decays using the L3 Detector
  Bose-Einstein correlations of pairs of identical charged pions produced in hadronic Z decays are analyzed in terms of various parametrizations. A good description is achieved using a Levy stable distribution in conjunction with a hadronization model having highly correlated configuration and momentum space, the tau-model. Using these results, the source function is reconstructed.
