Title
Kaon interference in the hadronic decays of the Z(0)
Author
Abstract
The first measurement of like-sign charged kaon correlations in hadronic decays of the Z(0) is presented, based on data collected by the DELPHI detector. The charged kaons are identified by means of ring imaging Cherenkov detectors. A significant enhancement at small values of the four-momentum difference is observed in the ratio of like-sign to unlike-sign KK pairs and in the ratio of like-sign pairs to a simulated reference sample. An update of the measurement of (KSKS0)-K-0 interference is also presented. An enhancement is found in the production of pairs of K-S(0) of similar momenta, as compared with a simulated reference sample. The measured Bose-Einstein correlation parameters lambda and r are similar for charged and neutral kaon pairs. The value of the Bose-Einstein correlation strength A is consistent with unity.
