The automated computation of tree-level and next-to-leading order differential cross sections, and their matching to parton shower simulations

TL;DR: MadGraph5 aMC@NLO as discussed by the authors is a computer program capable of handling all these computations, including parton-level fixed order, shower-matched, merged, in a unified framework whose defining features are flexibility, high level of parallelisation and human intervention limited to input physics quantities.

FeynRules 2.0 - A complete toolbox for tree-level phenomenology

TL;DR: FeynRules is a Mathematica-based package which addresses the implementation of particle physics models, which are given in the form of a list of fields, parameters and a Lagrangian, into high-energy physics tools.

UFO - The Universal FeynRules Output

TL;DR: An interface for the Mathematica package FeynRules that allows for an automatic output of models in the UFO format, which is flexible, modular and agnostic of any assumption such as the number of particles or the color and Lorentz structures appearing in the interaction vertices.

The anatomy of electroweak symmetry breaking: Tome I: The Higgs boson in the Standard Model

TL;DR: In this paper, the authors focused on the mechanism of electroweak symmetry breaking and the fundamental properties of the Higgs particle of the Standard Model and its decay modes and production mechanisms at hadron colliders and at future lepton colliders.
Journal ArticleDOI

Investigating the near-criticality of the Higgs boson

TL;DR: In this article, the parameters of the Higgs potential, the top Yukawa coupling and the electroweak gauge couplings were extracted from data with full 2-loop NNLO precision.

Automated one-loop calculations in four and D dimensions

TL;DR: In this article, two program packages for evaluating one-loop amplitudes are presented, which can work either in dimensional regularization or in constrained differential renormalization, and they are shown to be equivalent to regularization by dimensional reduction.
Journal ArticleDOI

Automatic Feynman graph generation

TL;DR: A general method is devised for the automatic generation of Feynman diagrams in gauge (and other) field theories and the performance of an implemented computer program is described.

Techniques for the calculation of electroweak radiative corrections at the one-loop level and results for W-physics at LEP200

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.
