Fermion pair production at LEP2 and interpretations
Preliminary results on ee → f f̄ , f = e, μ, τ, q, including all LEP2 data are discussed. Good agreement is found with the Standard Model up to the highest energies. Limits on possible new physics are extracted. Fermion pair production processes have been measured by the four LEP experiments up to √ s ≃ 207 GeV [1]. Above the Z peak γ radiation is very important, leading in particular to a high ...
متن کاملRadiative Corrections to W-pair Mediated Four-fermion Production at Lep2
as typical example, but all four-fermion final states originating from W -boson pairs can be treated in a similar way. Since the RADCOR 98 conference took place our results have been finalized and discussed elsewhere . A highlight of the main points is given here. For related issues, see these proceedings . A complete calculation of O(α) radiative corrections to a process with six external part...
متن کاملFour-Fermion Production with Anomalous Couplings at LEP2 and NLC1
I give a short report on the semi-analytical approach to off-shell W pair production. In particular, I show the effects of irreducible background diagrams of the CC11 class in the differential cross-section. Further, I study the influence of potential anomalous couplings at a future linear collider and investigate the sensitivity of the forward-backward asymmetry to anomalous couplings. Talk gi...
متن کاملPRECISE 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.
متن کاملRadiative four–fermion processes at LEP2
The production of four fermions plus a visible photon in electron-positron collisions is analyzed in the LEP2 energy range. The study is based on the calculation of exact matrix elements, including the effect of fermion masses. In the light of the present measurements performed at LEP, triple and quartic anomalous gauge couplings are taken into account. Due to the presence of a visible photon i...
