Higgs Production via Weak Boson Fusion in the Standard Model and the MSSM

TL;DR: In this article, the dominant supersymmetric one-loop corrections to neutral Higgs production, in the general case where the MSSM includes complex phases, have been calculated by calculating the full virtual electroweak corrections and photon radiation and implementing these results into the public Monte Carlo program VBFNLO.

Electroweak corrections to monojet production at the Tevatron and the LHC

TL;DR: In this article, the authors presented the calculation of the full next-to-leading-order (NLO) electroweak corrections and a recalculation of the NLO QCD corrections to monojet production at the Tevatron and the LHC.

The Rational Part of QCD Amplitude I: the General Formalism

TL;DR: In this paper, a general formalism for computing rational part of the one-loop QCD amplitude is developed, starting from the Feynman integral representation, using tensor reduction and recursive relations to compute the rational part directly.

Radiative corrections to the Triple Higgs Coupling in the Inert Higgs Doublet Model

TL;DR: In this article, the effect of radiative corrections to the triple Higgs coupling and to hZZ, hW W couplings in the context of the Inert Higgs Doublet Model (IHDM) was investigated.

Regularization and Renormalization of Gauge Fields

TL;DR: In this article, a new regularization and renormalization procedure for gauge theories is presented, which is particularly well suited for the treatment of gauge theories and is transparent when anomalies such as the Bell-Jackiw-Adler anomaly may occur.

Feyn Calc - Computer-algebraic calculation of Feynman amplitudes

TL;DR: Feyn Calc as discussed by the authors is a computer program for automatic algebraic calculation of Feynman amplitudes, which can be used to calculate tree level diagrams as well as 1-and 2-loop corrections in the Standard Model.

Supersymmetric Dimensional Regularization via Dimensional Reduction

TL;DR: In this article, a modified form of dimensional regularization is introduced which manifestly preserves gauge invariance, unitarity, and global supersymmetry, and also considers its application to supergravity.

Techniques for the Calculation of Electroweak Radiative Corrections at the One-Loop Level and Results forW-physics at LEP 200

TL;DR: In this paper, a review of the techniques necessary for the calculation of virtual electroweak and soft photonic corrections at the one-loop level is presented. And the full set of analytical formulae and corresponding numerical results for the decay width of the W-boson and the top quark are presented.
