摘要：

K(S)0K(S)0 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(S)0 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 lambda = 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(S)0K(S)0 pairs display an enhancement, regardless of whether they come from a K0K0BAR or from a K0K0 (K0K0BAR) system.
