Abstract

Two-particle correlations in pp, and 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, pairs a depletion of events is observed in the region Q<3 GeV, and for 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.
