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…
Master integrals for semi-inclusive cuts of massless four-loop propagators
Vitaly Magerya, Levente Fekésházy
We present the analytic calculation of all master integrals for 3-, 4-, and 5-particle semi-inclusive cuts of four-loop massless propagators by means of differential equations. We…
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…
Two-loop amplitudes for ttH production: the quark-initiated Nf-part
Bakul Agarwal, Gudrun Heinrich, Stephen P. Jones +5
We present numerical results for the two-loop virtual amplitude entering the NNLO corrections to Higgs boson production in association with a top quark pair at the LHC, focusing, a…
Evaluating scattering amplitudes with pySecDec 1.6
Vitaly Magerya
pSecDec is a computer tool to evaluate Feynman integrals and their weighted sums (amplitudes) using the method of sector decomposition and numerical integration. The new release of…
Machine Learning and LHC Event Generation
Anja Butter, Tilman Plehn, Steffen Schumann +48
First-principle simulations are at the heart of the high-energy physics research program. They link the vast data output of multi-purpose detectors with fundamental theory predicti…
