Abstract: (Elsevier)
Two-particle correlations in pp, p¯p¯ and KS0KS0 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, p¯p¯ pairs a depletion of events is observed in the region Q<3 GeV , and for KS0KS0 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.- electron positron: colliding beams
- electron positron: annihilation
- Z0: electroproduction
- Z0: hadronic decay
- hadron: multiple production
- correlation: two-particle
