Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

The precision frontier in collider physics is being pushed at impressive speed, from both the
experimental and the theoretical side. The aim of this review is to give an overview of recent …

We present the computational framework Matrix (http://matrix. hepforge. org/) which allows
us to evaluate fully differential cross sections for a wide class of processes at hadron …

We provide an overview of the status of Monte-Carlo event generators for high-energy
particle physics. Guided by the experimental needs and requirements, we highlight areas of …

We compute the next-to-next-to-leading order (NNLO) quantum chromodynamics (QCD)
correction to the total cross section for the reaction gg→ tt¯+ X. Together with the partonic …

This Report summarizes the results of the activities in 2012 and the first half of 2013 of the
LHC Higgs Cross Section Working Group. The main goal of the working group was to …

Charged gauge boson pair production at the Large Hadron Collider allows detailed probes
of the fundamental structure of electroweak interactions. We present precise theoretical …

Without proper control of numerical and methodological errors in theoretical predictions at
the per mille level it is not possible to study the effect of input parameters in current hadron …

We compute the next-to-leading-order QCD corrections to the production of two Z-bosons in
the annihilation of two gluons at the LHC. Being enhanced by a large gluon flux, these …

We report on the first calculation of next-to-next-to-leading order (NNLO) QCD corrections to
the inclusive production of Z-boson pairs at hadron colliders. Numerical results are …
