Abstract: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 hadronization model having highly correlated configuration and momentum space, the τ-model. Using these results, the source function is reconstructed.
“…(In fact for an evolving system such as a heavy ion collision, it is not really a surface, since at each time there is a spread out surface due to fluctuations in the last scattering position, and the shape of the surface evolves in time. ) Metzger presented a remarkable analysis of data from the L3 detector at LEP [36]. By a very detailed analysis he showed that deviations from a Gaussian parameterization demonstrated that the the space-time surface of decoupling is consistent with inside-outside cascade dynamics.…”
