Multiloop Integrand Reduction for Dimensionally Regulated Amplitudes
P. Mastrolia, E. Mirabella, G. Ossola +1
We present the integrand reduction via multivariate polynomial division as a natural technique to encode the unitarity conditions of Feynman amplitudes. We derive a recursive formu…
NLO QCD corrections to the production of Higgs plus two jets at the LHC
H. van Deurzen, N. Greiner, G. Luisoni +6
We present the calculation of the NLO QCD corrections to the associated production of a Higgs boson and two jets, in the infinite top-mass limit. We discuss the technical details o…
Handbook of LHC Higgs Cross Sections: 3. Higgs Properties
The LHC Higgs Cross Section Working Group, S. Heinemeyer, C. Mariotti +155
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 pres…
Event Generators for High-Energy Physics Experiments
J. M. Campbell, M. Diefenthaler, T. J. Hobbs +209
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 acti…
GoSam applications for automated NLO calculations
G. Cullen, H. van Deurzen, N. Greiner +10
We present applications of the program GoSam for the automated calculation of one-loop amplitudes. Results for NLO QCD corrections to beyond the Standard Model processes as well as…
Analytic form of the full two-loop five-gluon all-plus helicity amplitude
S. Badger, D. Chicherin, T. Gehrmann +6
We compute the full-color two-loop five-gluon amplitude for the all-plus helicity configuration. In order to achieve this, we calculate the required master integrals for all permut…

G. Cullen, H. van Deurzen, N. Greiner +10
After reviewing the main features of the GoSam framework for automated one-loop calculations, we present a selection of recent phenomenological results obtained with it. In particu…
NLO QCD corrections to Higgs boson production plus three jets in gluon fusion
G. Cullen, H. van Deurzen, N. Greiner +6
We report on the calculation of the cross section for Higgs boson production in association with three jets via gluon fusion, at next-to-leading-order (NLO) accuracy in QCD, in the…
To , or not to : Recent developments and comparisons of regularization schemes
C. Gnendiger, A. Signer, D. Stöckinger +16
We give an introduction to several regularization schemes that deal with ultraviolet and infrared singularities appearing in higher-order computations in quantum field theories. Co…
The Integrand Reduction of One- and Two-Loop Scattering Amplitudes
P. Mastrolia, E. Mirabella, G. Ossola +2
The integrand-level methods for the reduction of scattering amplitudes are well-established techniques, which have already proven their effectiveness in several applications at one…
GoSam-2.0: a tool for automated one-loop calculations within the Standard Model and beyond
G. Cullen, H. van Deurzen, N. Greiner +9
We present the version 2.0 of the program package GoSam for the automated calculation of one-loop amplitudes. GoSam is devised to compute one-loop QCD and/or electroweak correction…
Automated one-loop calculations with GoSam 2.0
H. van Deurzen, N. Greiner, G. Heinrich +8
We present the version 2.0 of the program GoSam, which is a public program package to compute one-loop corrections to multi-particle processes. The extended version of the "Binoth-…
