متن کاملEffects of Fsi, Cr and Bec at Small Relative Momenta of Particles and W-mass Systematics at Lep
The observation of the enhanced production of like–sign particle pairs by LEP experiments at Z does not insure that the observed correlations owe their origin to Bose-Einstein correlations(BEC). They could, for example, arise from final state interactions(FSI) between pions with small relative momenta. (we recommend not to call BEC and/or Colour Reconnection as ’FSI effects’ as it is generally ...
متن کاملModelling Bose – Einstein correlations at LEP 2 Leif
We present new algorithms for simulating Bose–Einstein correlations among final-state bosons in an event generator. The algorithms are all based on introducing Bose–Einstein correlations as a shift of final-state momenta among identical bosons, and differ only in the way energy and momentum conservation is ensured. The benefits and shortcomings of this approach, that may be viewed as a local re...

The studies of Fermi–Dirac correlations of ΛΛ and ¯ Λ ¯ Λ pairs in hadronic Z decays, Bose–Einstein correlations and colour reconnection in W-pairs decays performed by the ALEPH collaboration in e + e − annihilation at LEP are presented. The OPAL analysis of Bose–Einstein correlations in W-pair decays is also discussed.
متن کاملFinal State Interactions in Hadronic Ww Decay at Lep
An overview is given of the study of final state interactions in hadronically decaying W pairs produced in ee-collisions as it is performed by the four LEP experiments. Bose-Einstein correlations are investigated by comparing likewith unlike-signed pairs of pions and/or using the mixed event analysis technique. Colour reconnection is examined with a method that compares the particle flow distri...
