Colour Reconnection at Lep
Two measurements are presented of estimators sensitive to the Colour Reconnection effect in WW events at LEP2. The results are compared with various phenomenological Monte Carlo implementations of the effect. A feasibility study is performed to reduce the total uncertainty in the direct mW measurement at LEP2 by use of the inferred information about the Colour Reconnection effect.
متن کاملColour Reconnection at Lep2
The preliminary results on the search of colour reconnection effects (CR) from the four experiments at LEP, Aleph, Delphi, L3 and Opal, are reviewed. Extreme models are excluded by studies of standard variables, and on going studies of a method first suggested by L3, the particle flow method 1 , are yet inconclusive.
متن کاملColour Reconnection in W Decays
The studies of colour reconnection in ee → WW → qq̄qq̄ events at LEP are reviewed. It is shown that the analysis of the particleand energy flow between jets is sensitive to realistic model predictions. The effects on the W mass measurement are discussed. Most results are preliminary. 1 Colour Reconnection With some 450 pb per experiment already recorded at √ s = 183− 202 GeV, and more to come at ...
متن کاملColour Reconnection at Future e+e− Colliders
The effects of colour reconnection (CR) at e+e− colliders are revisited, with focus on recently developed CR models. The new models are compared with the LEP2 measurements for e+e− → W+W− → q1q2q3q4 and found to lie within their limits. Prospects for constraints from new high-luminosity e+e− colliders are discussed. The novel arena of CR in Higgs decays is introduced, and illustrated by shifts ...
متن کاملColour reconnection and Bose-Einstein effects
Final-state interactions and interference phenomena that could affect the value of the W mass reconstructed from hadronic WW decays at LEP2 are reviewed, and possible areas for future investigation are identified.
