Electroweak radiative corrections to e + e − → tt̄H

چکیده
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 genuine weak corrections reach the order of about 10% or even more and show a non-trivial dependence on the Higgs-boson mass and on the scattering energy. We compare our results with two previous calculations that obtained differing results at high energies.

Radiative corrections to Higgs-boson production in association with top-quark pairs at ee colliders
We have calculated the complete O(α) and O(αs) radiative corrections to the Higgsproduction process e+e− → tt̄H in the Standard Model. This process is particularly interesting for the measurement of the top-quark Yukawa coupling at a future e+e− collider. The calculation of the O(α) corrections is described in some detail including, in particular, the treatment of the soft and collinear singular...
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...
متن کاملZFITTER: a semi-analytical program for fermion pair production in e+e- annihilation, from version 6.21 to version 6.42
ZFITTER is a Fortran program for the calculation of fermion pair production and radiative corrections at high energy e+e− colliders; it is also suitable for other applications where electroweak radiative corrections appear. ZFITTER is based on a semi-analytical approach to the calculation of radiative corrections in the Standard Model. We present a summary of new features of the ZFITTER program...
متن کاملRacoonWW1.3: A Monte Carlo program for four-fermion production at e+e− colliders
We present the Monte Carlo generator RacoonWW that computes cross sections to all processes e+e− → 4f and e+e− → 4fγ and calculates the complete O(α) electroweak radiative corrections to e+e− → WW → 4f in the electroweak Standard Model in double-pole approximation. The calculation of the tree-level processes e+e− → 4f and e+e− → 4fγ is based on the full matrix elements for massless (polarized) ...
