Title
Particle correlations in $e^{+}e^{-}\rightarrow W^{+}W^{-}$ events
Author
Abstract
 Preliminary results are reported on the two-particle correlation function R(Q) in hadronic Z decays. fully hadronic WW decays, and mixed hadronic-leptonic WW decays using data collected by the DELPHI detector at LEP at energies between 189 and 206 GeV. Evidence for Bose-Einstein correlations was observed in all three cases. The event mixing technique was used to determine correlations between particles arising from different W bosons in fully hadronic WW decays. An excess of like-sign particle pairs with low four-momentum difference in fully hadronic WW events is observed, consistent with the effect expected from correlations between identical particles from different W bosons.
