GoSam @ LHC: algorithms and applications to Higgs production
G. Cullen, H. van Deurzen, N. Greiner +10
We elaborate on GoSam, a code-writer for automated one-loop calculations. After recalling its main features, we present a selection of phenomenological results recently obtained, g…
Multi-loop Integrand Reduction via Multivariate Polynomial Division
Hans van Deurzen, Gionata Luisoni, Pierpaolo Mastrolia +4
We present recent developments on the topic of the integrand reduction of scattering amplitudes. Integrand-level methods allow to express an amplitude as a linear combination of Ma…
Multi-leg One-loop Massive Amplitudes from Integrand Reduction via Laurent Expansion
Hans van Deurzen, Gionata Luisoni, Pierpaolo Mastrolia +3
We present the application of a novel reduction technique for one-loop scattering amplitudes based on the combination of the integrand reduction and Laurent expansion. We describe…
NLO QCD Production of Higgs boson plus jets with GoSam
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…
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…
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…
