NLO corrections to squark-squark production and decay at the LHC

TL;DR: In this paper, the authors present an analysis of the signature 2j + T via squark-squark production and direct decay into the lightest neutralino, in next-to-leading order QCD within the framework of the minimal supersymmetric standard model.

Loop Induced Single Top Partner Production and Decay at the LHC

TL;DR: In this article, the authors study the signature of the top partner produced in association with the SM top, and show that with reasonable coupling strengths, the production rate of this channel can dominate top partner pair production at top partner masses of mT ≳ 1.5 TeV.

Muon specific two-Higgs-doublet model

TL;DR: In this paper, a softly-broken two-Higgs-doublet model was proposed to restrict the structure of Yukawa couplings, which can explain the muon g − 2 anomaly within the 1σ level satisfying constraints from perturbative unitarity, vacuum stability, electroweak precision measurements, and current LHC data.

Matching Squark Pair Production at NLO with Parton Showers

TL;DR: In this article, the authors present a fully dierential calculation of the next-to-leading order (NLO) SUSYQCD corrections to the on-shell production of a pair of squarks in the Minimal Supersymmetric Standard Model (MSSM), supplemented by the leading-order decay of the squarks to the lightest neutralino and a quark.

The beta function of N=1 SYM in differential renormalization

TL;DR: In this article, the complete two-point function of the background gauge superfield in pure N = 1 supersymmetric Yang-Mills theory to two loops was calculated using differential renormalization, and the connection of the beta function to the flow of the wilsonian coupling was discussed.

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.

Automatic generation of tree level helicity amplitudes

TL;DR: The program MadGraph is presented which automatically generates postscript Feynman diagrams and Fortran code to calculate arbitrary tree level helicity amplitudes by calling HELAS[1] subroutines.
