A resonance-aware MC@NLO QCD+EW-matched calculation of lepton-pair production
Lois Flower, Joanne Roper, Marek Schönherr
As we approach HL-LHC, there is a growing need for increased precision in theoretical predictions so that meaningful comparisons with experimental data can be made. It is no longer…
at NLO EW matched to a QED parton shower
Lois Flower, Marek Schönherr
To prepare for the next generation particle collider, likely to be a high-energy precision-frontier electron-positron machine, theoretical predictions must improve in tandem. One a…
Accelerating LHC event generation with simplified pilot runs and fast PDFs
Enrico Bothmann, Andy Buckley, Ilektra A. Christidi +5
Poor computing efficiency of precision event generators for LHC physics has become a bottleneck for Monte-Carlo event simulation campaigns. We provide solutions to this problem by…
Initial state QED radiation aspects for future colliders
S. Frixione, E. Laenen, C. M. Carloni Calame +25
This white paper concerns theoretical and phenomenological aspects relevant to the physics of future colliders, in particular regarding initial-state QED radiation. The co…
Precise predictions for V+2 jet backgrounds in searches for invisible Higgs decays
Jonas M. Lindert, Stefano Pozzorini, Marek Schönherr
We present next-to-leading order QCD and electroweak (EW) theory predictions for jet production, with , considering both the QCD and EW production modes and the…
HL-LHC Computing Review: Common Tools and Community Software
HEP Software Foundation, :, Thea Aarrestad +107
Common and community software packages, such as ROOT, Geant4 and event generators have been a key part of the LHC's success so far and continued development and optimisation will b…
Constraining SMEFT operators with associated production in Weak Boson Fusion
Anke Biekötter, Raquel Gomez-Ambrosio, Parisa Gregg +2
We consider the associated production of a Higgs boson and a photon in weak boson fusion in the Standard Model (SM) and the Standard Model Effective Theory (SMEFT), with the Higgs…
Event Generation with Sherpa 2.2
Enrico Bothmann, Gurpreet Singh Chahal, Stefan Höche +9
Sherpa is a general-purpose Monte Carlo event generator for the simulation of particle collisions in high-energy collider experiments. We summarize essential features and improveme…
Modelling and tuning in top quark physics

In this proceedings I discuss the general strategy and impact of tuning Monte-Carlo event generators for physics processes involving top quarks. Special emphasis is put on disingui…
NNLO versus NLO multi-jet merging for top-pair production including electroweak corrections
