Electroweak Radiative Corrections at High Energies

چکیده
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.

Weak Boson Emission in Hadron Collider Processes
The O(α) virtual weak radiative corrections to many hadron collider processes are known to become large and negative at high energies, due to the appearance of Sudakov-like logarithms. At the same order in perturbation theory, weak boson emission diagrams contribute. Since the W and Z bosons are massive, the O(α) virtual weak radiative corrections and the contributions from weak boson emission ...

The Large Hadron Collider (LHC) will study processes at energies √ s much larger than the masses of the W and Z bosons. Radiative (Sudakov) corrections to such processes contain logarithms L = log(s/M W,Z), and one gets two factors of L for each order in perturbation theory [1]. At LHC energies, these Sudakov corrections are not small — a typical electroweak correction αL/(4π sin θW ) ∼ 0.15 at...
متن کاملOne-loop leading logarithms in electroweak radiative corrections I. Results
We present results for the complete one-loop electroweak logarithmic corrections for general processes at high energies and fixed angles. Our results are applicable to arbitrary matrix elements that are not mass-suppressed. We give explicit results for 4-fermion processes and gauge-boson-pair production in ee annihilation.
متن کاملElectroweak radiative corrections to e + e − → tt̄H
We have calculated the complete electroweak O(α) radiative corrections to the Higgs-boson production process e + e − → t ¯ tH in the electroweak Standard Model. Initial-state radiation beyond O(α) is included in the structure-function approach. The calculation of the corrections is briefly described, and numerical results are presented for the total cross section. Both the photonic and the genu...
متن کاملElectroweak 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...
