Abstract: (Elsevier)
K 0 S K 0 S correlations have been studied in a sample of 717 511 hadronic events collected by the DELPHI detector at LEP during 1992. An enhancement is found in the production of pairs of K 0 S of similar momenta, as compared with a Monte Carlo simulated reference sample. The measured values for the strength of the correlation and the radius of the emitting source of kaons are λ = 1.13 ± 0.54 (stat) ± 0.23 (syst) and r = 0.90 ± 0.19 (stat) ± 0.10 (syst) fm. This enhancement is consistent with the hypothesis that K 0 S K 0 S pairs display an enhancement, regardless of whether they come from a K 0 K̄ 0 or from a K 0 K 0 (K̄ 0 K̄ 0 ) system.- electron positron: colliding beams
