Perturbative QCD
Gudrun Heinrich, Anton Olsson
We give an introduction to perturbative Quantum Chromodynamics, focusing on a pedagogical description of concepts and methods to calculate cross sections measured at high energy co…
One-Loop Calculations in Effective Field Theories with GoSam-3.0
Jens Braun, Benjamin Campillo Aveleira, Gudrun Heinrich +5
We present a major update of the one-loop generator GoSam, containing performance improvements as well as new features, in particular functionalities that facilitate calculations b…
Interpolating amplitudes
Víctor Bresó, Gudrun Heinrich, Vitaly Magerya +1
The calculation of scattering amplitudes at higher orders in perturbation theory has reached a high degree of maturity. However, their usage to produce physical predictions within…
Numerical Scattering Amplitudes with pySecDec
G. Heinrich, S. P. Jones, M. Kerner +3
We present a major update of the program pySecDec, a toolbox for the evaluation of dimensionally regulated parameter integrals. The new version enables the evaluation of multi-loop…
Expansion by regions with pySecDec
G. Heinrich, S. Jahn, S. P. Jones +6
We discuss the technique of expansion by regions from a geometric perspective, and its implementation within pySecDec, a toolbox for the evaluation of dimensionally regulated param…
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-…
