Descripción
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 Lévy stable distribution in conjunction with a model where a particle’s momentum is correlated with its space–time point of production, the τ -model. Us- ing this description and the measured rapidity and transverse momentum distributions, the space–time evolution of par- ticle emission in two-jet events is reconstructed. However, the elongation of the particle emission region previously ob- served is not accommodated in the τ -model, and this is in- vestigated using an ad hoc modification.
