Wigner Functions in High Energy Physics

Recent developments are (meta)reviewed in the applications of Wigner functions to describe the observed single particle spectra and two-particle Bose-Einstein (or Hanbury Brown -- Twiss) correlations in high energy particle and nuclear physics, with examples from hadron-proton and Pb + Pb collisions at CERN SPS.Comment: 4 pages, invited talk at the Wigner Centennial Conference, Pecs, Hungary, July 200

Analytic calculation of Bose-Einstein correlations at LEP1 and LEP2

Theoretical results in the tau-model are discussed in the context of Bose-Einstein correlations in e+e- annihilations at LEP1 and LEP2 as well as that of relativistic heavy ion collisions at SPS and RHIC.Comment: 4 pages, invited talk at the XXXIIth Int. Symp. Multiparticle Dynamics, Alushta, Crimea, Ukrain
