Shortest movie: Bose-Einstein correlation functions in e+e- annihilations

Abstract

Bose-Einstein correlations of identical charged-pion pairs produced in hadronic Z decays are analyzed in terms of various parametrizations. A good description is achieved using Levy stable distributions. The source function is reconstructed with the help of the tau-model.Comment: 6 pages, 3 figures, presented at the 5th Budapest Winter School on Heavy Ion Physic
