Fluctuations and Fermi-Dirac Correlations in e+e- annihilation

Abstract

In this talk I first present a short review of fluctuations in $e^{+}{e}^{-}$-annihilations. I then describe some new results on FD correlations. Experimental analyses of $pp$ and $\Lambda \Lambda$ correlations indicate a very small production radius. This result relies very strongly on comparisons with MC simulations. A study of the approximations and uncertainties is these simulations imply that it is premature to draw such a conclusion from the data.
