| Résumé : | KS 0KS 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 KS 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 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 KS 0KS 0 pairs display an enhancement, regardless of whether they come from a K0K̄0 or from a K0K0 (K̄0K̄0) system. |
