Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

Jet substructure has emerged to play a central role at the Large Hadron Collider (LHC),
where it has provided numerous innovative new ways to search for new physics and to …

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 …

This manual describes the Pythia event generator, the most recent version of an evolving
physics tool used to answer fundamental questions in particle physics. The program is most …

We provide an overview of the status of Monte-Carlo event generators for high-energy
particle physics. Guided by the experimental needs and requirements, we highlight areas of …

Parton showers are among the most widely used tools in collider physics. Despite their key
importance, none so far have been able to demonstrate accuracy beyond a basic level …

The successful operation of the Large Hadron Collider (LHC) and the excellent performance
of the ATLAS, CMS, LHCb and ALICE detectors in Run-1 and Run-2 with $ pp $ collisions at …

A bstract Lund diagrams, a theoretical representation of the phase space within jets, have
long been used in discussing parton showers and resummations. We point out that they can …

This Report summarizes the proceedings of the 2019 Les Houches workshop on Physics at
TeV Colliders. Session 1 dealt with (I) new developments for high precision Standard Model …

A bstract We present a novel method to combine QCD calculations at next-to-next-to-leading
order (NNLO) with parton shower (PS) simulations, that can be applied to the production of …
