چکیده

The results on ee → WW → 4f(+γ) obtained by different groups are compared with each other. Differences in the results for the total cross section of up to about 0.6 % are traced back to different ways of implementing the double-pole approximation.

Electroweak Precision Physics at ee Colliders with RacoonWW

We present precise predictions for the processes ee → WW → 4f(γ) at LEP2 and future Linear-Collider (LC) energies obtained with the Monte Carlo generator RacoonWW. The program RacoonWW includes the complete O(α) electroweak radiative corrections to ee → WW → 4f in the double-pole approximation (DPA). While the virtual corrections are treated in DPA, the calculation of the bremsstrahlung correct...

PRECISE PREDICTIONS FOR W-PAIR PRODUCTION AT LEP2 WITH RacoonWW

RacoonWW is the first Monte Carlo generator for ee → WW → 4f(+γ) that includes the electroweak O(α) radiative corrections in the double-pole approximation completely. Some numerical results for LEP2 energies are discussed, and the predictions for the total W-pair cross section are confronted with LEP2 data.

Precise predictions for e + e − → 4 f ( + γ ) with anomalous couplings ∗

The relevance of radiative corrections to 4f production at LEP2 and future ee colliders is emphasized, and their treatment in the event generator RacoonWW is briefly discussed. In particular, the non-universal corrections are compared with the signature of anomalous triple gauge-boson couplings. For 4f +γ production the influence of anomalous quartic gauge-boson couplings on photon-energy distr...

→ W + W − γ at LEP 2 and NLC

We present sensitivity limits on the coefficients of a dimension–6 effective Lagrangian that parametrizes the possible effects of new physics beyond the Standard Model. Our results are based on the study of the process e + e − → W + W − γ at LEP2 and NLC energies. In our calculations, we include all the new anomalous interactions, involving vector and Higgs bosons, and take into account the Sta...
