The inseparable three and four tops
Gauthier Durieux, Hesham El Faham, Rikkert Frederix +2
The paper presents a complete next-to-leading order calculation of three‑top production with a W boson (tttW) and its overlap with four‑top production (tttt) at the LHC, introducin…
MAcNLOPS for ZZ Pair Production at the LHC
Yuxiao Che, Rikkert Frederix
We present an implementation of the MAcNLOPS matching prescription for production in a MadGraph5_aMC@NLO + Pythia8 setup. Starting from a standard MC@NLO event sample,…
MC@NLO event generation by reweighting unweighted Born events
Saad El Farkh, Rikkert Frederix, Mohamed Gouighri
We propose a computational strategy for NLO+PS simulations in the MC@NLO framework that starts from Born-accurate (LO) events and reweights them to the full MC@NLO S-event weight,…
A multi-event interface for next-to-leading order calculations in MadGraph5_aMC@NLO
Rikkert Frederix, Stefan Roiser, Robert Schöfbeck +2
We detail the implementation of a multi-event interface for next-to-leading order (NLO) calculations in MadGraph5_aMC@NLO, allowing tree-level scattering amplitudes for multiple ph…
Event generation with exponential scaling in multiplicity using AmpliCol
Rikkert Frederix, Timea Vitos
Efficient generation of LHC events is hindered by the rapidly rising cost of evaluating QCD matrix elements with increasing multiplicity. We build on a recently proposed two-step s…
FASTColor -- Full-color Amplitude Surrogate Toolkit for QCD
Javier Mariño Villadamigo, Rikkert Frederix, Tilman Plehn +2
High-multiplicity events remain a bottleneck for LHC simulations due to their computational cost. We present a ML-surrogate approach to accelerate matrix element reweighting from l…
