  In hadronic Z decays, Bose-Einstein correlations in neutral pion pairs are
compared to those in identical charged pion pairs. Bose-Einstein correlations
are also measured in triplets of identical charged pions, and comparison with
those in pairs of pions indicates that pion production is completely
incoherent. Further, factorial cumulants are used to compare correlations among
like-sign as well as among all particles with those of several Monte Carlo
models.
