Resonance-aware electroweak Sudakov reweighting for multijet-merged predictions
Lenart Jerala, Rikkert Frederix, Miha Muškinja +3
We present a resonance-aware extension of electroweak Sudakov-logarithm reweighting in MadGraph5_aMC@NLO for NLO QCD-matched and FxFx multijet-merged event samples. The method iden…
Simulations and flavour-scheme studies for Higgs-boson production in association with charm quarks
Tiziano Bevilacqua, Christian Biello, Lea Michela Caminada +5
We present a detailed NLO+PS study of Higgs-boson production in association with charm and bottom quarks, with particular focus on the modelling of the H+c final state. We systemat…
The inseparable three and four tops
Gauthier Durieux, Hesham El Faham, Rikkert Frederix +2
In measurements of four-top-quark production (), LHC collaborations observe a significant degeneracy with three-top-quark production. We compute the dominant three-top-produc…
MadNIS at NLO
Giovanni De Crescenzo, Javier Mariño Villadamigo, Nina Elmer +4
We combine fast amplitude surrogates with neural importance sampling to accelerate NLO calculations. For virtual corrections, a learned ratio to the Born matrix element with calibr…
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…
