For Electroweak Corrections ?

چکیده
The Born approximation, based on ¯ α ≡ α(m Z) instead of α, reproduces all electroweak precision measurements within their (1σ) accuracy. The low upper limits for the genuinely electroweak corrections constitute one of the major achievements of LEP. The astonishing smallness of these corrections results from the cancellation of a large positive contribution from the heavy top quark and large negative contributions from all other virtual particles. It is precisely the non-observation of electroweak radiative corrections that places stringent upper and lower limits on the top mass.

Electroweak Radiative Corrections at High Energies
For energies far above the electroweak scale, large electroweak radiative corrections occur that grow logarithmically with energy and can easily reach several tens of per cent in the TeV range. Recent work on these corrections is reviewed.
متن کاملElectroweak Radiative Corrections to W Boson Production in Hadronic
The O(α) electroweak radiative corrections to the process p p (ℓ = e, µ) are calculated. The O(α) corrections can be decomposed into separately gauge invariant contributions to the W boson production and decay processes. Factorizing the collinear singularity associated with initial state photon radiation into the parton distribution functions, we find that initial state corrections have a signi...

We have calculated the O(αewM 2 t /M 2 W ) supersymmetric electroweak corrections to single top quark production via qq̄ → tb̄ at the Fermilab Tevatron in the minimal supersymmetric model. The supersymmetric electroweak corrections to the cross section are a few percent for tanβ > 1, and can exceed 10% for tanβ < 1. The combined effects of SUSY electroweak corrections and the Yukawa corrections c...
متن کاملElectroweak Theory and the 1996/97 Precision Electroweak Data * †
We review the empirical evidence for the validity of the Standard Electroweak Theory in Nature. The experimental data are interpreted in terms of an effective Lagrangian for Z physics, allowing for potential sources of SU(2) violation and containing the predictions of the Standard Electroweak Theory as a special case. Particular emphasis is put on discriminating loop corrections due to fermion-...
متن کاملSupersymmetric Electroweak Corrections to W±H∓ Associated Production at the CERN Large Hadron Collider
The O(αewm 2 t(b)/m 2 W ) and O(αewm 4 t(b)/m 4 W ) supersymmetric electroweak corrections to the cross section for WH associated production at the LHC are calculated in the minimal supersymmetric standard model. Those corrections arise from the quantum effects which are induced by the Yukawa couplings from the Higgs sector and the chargino-top(bottom)-sbottom(stop) couplings, neutralinotop(bot...
