Radiative Corrections to E Radiative Corrections to E

We study the 1-loop corrections to the charged Higgs production both in the Minimal Supersymmetric Standard Model (MSSM) and in a more general type II two-Higgs-doublet model (THDM-II). We consider the full set of corrections (including soft photon contributions as well as box diagrams), and define a parametrization that allows a comparison between the two models. Besides the soft photon radiat...

Electroweak radiative corrections to e + e − → νν̄

The complete electroweak O(α) radiative corrections to the Higgs-boson production processes e+e− → νlν̄lH (l = e, μ, τ) are calculated in the electroweak Standard Model. For e+e− → νeν̄eH, where ZH production and W-boson fusion contribute, both production channels are added coherently. The calculation of the corrections is described in some detail including, in particular, the treatment of the Z-...

Electroweak 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...

Radiative corrections to e + e − → WW → 4 fermions †

The structure of the double-pole approximation for the O(α) corrections to e + e − → WW → 4 fermions is described, and some results are presented. Moreover, results on full tree-level predictions for e + e − → 4 fermions+γ are given.
