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” …

Current particle phenomenology is characterized by the spectacular agreement of the
predictions of the Standard Model of particle physics (SM) with all results from collider …

We present the library Collier for the numerical evaluation of one-loop scalar and tensor
integrals in perturbative relativistic quantum field theories. The code provides numerical …

We analyze constraints from perturbative unitarity and crossing on the leading contributions
of higher-dimension operators to the four-graviton amplitude in four spacetime dimensions …

This Report summarises the results of the second year's activities of the LHC Higgs Cross
Section Working Group. The main goal of the working group was to present the state of the …

Two program packages are presented for evaluating one-loop amplitudes. They can work
either in dimensional regularization or in constrained differential renormalization. The latter …

We present a technique which utilizes unitarity and collinear limits to construct ansätze for
one-loop amplitudes in gauge theory. As an example, we obtain the one-loop contribution to …

We review the techniques necessary for the calculation of virtual electroweak and soft
photonic corrections at the one‐loop level. In particular we describe renormalization …

SPheno is a program that accurately calculates the supersymmetric particle spectrum within
a high scale theory, such as minimal supergravity, gauge mediated supersymmetry …

We present the program package GoSam which is designed for the automated calculation of
one-loop amplitudes for multi-particle processes in renormalisable quantum field theories …
