Sumario:Bose-Einstein correlations of pairs of identical charged pions produced in ha- dronic Z decays are analyzed in terms of various parametrizations. A good descrip- tion is achieved using a L ́evy stable distribution in conjunction with a model where a particle’s momentum is correlated with its space-time point of production, the tau-model. Using this description and the measured rapidity and transverse momen- tum distributions, the space-time evolution of particle emission in two-jet events is reconstructed. However, the elongation of the particle emission region previously observed is not accommodated in the τ-model, and this is investigated using an ad hoc modification.
