Description
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 conguration and momentum space, the tau-model. Using these results, the time evolution of particle emission in two-jet events is reconstructed.
Previous studies have found an elongated shape of the source along the event axis while tau-model prefers a spherical shape. Elongaton is also found using the tau-model equations modified ad hoc to allow elongation. Hence new theoretical improvements of the tau model are needed.
