Applying EFT to Higgs Pair Production in Universal Extra Dimensions

TL;DR: In this paper, the authors investigate single Higgs and Higgs pair production at the LHC in models of Universal Extra Dimensions (UED) and use the UED model as a testing ground for the Effective Field Theory approach to physics beyond the Standard Model.

One loop corrections on fragmentation function of 1S wave charmed mesons

TL;DR: In this paper, the contribution of the next to leading order (NLO) corrections in fragmentation of a c-quark to 1S wave charmed mesons is presented, which is calculated by using the dimensional regularization method.

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.
