Two-particle correlations in pp,pp and K 0 S K 0 S pairs have been studied in hadronic Z decays recorded at LEP with the ALEPH detector. The correlations were measured as a function of the four-momentum difference Q of the pair. For pp,pp pairs a depletion of events is observed in the region Q < 3 GeV, and for K 0 S K 0 S pairs an enhancement of events is observed in the region Q < 0.5 GeV. These features are consistent with expectations from Fermi-Dirac and Bose-Einstein statistics, respectively.
