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” …

We review the physics basis, main features and use of general-purpose Monte Carlo event
generators for the simulation of proton–proton collisions at the Large Hadron Collider …

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 …

Abstract Particles beyond the Standard Model (SM) can generically have lifetimes that are
long compared to SM particles at the weak scale. When produced at experiments such as …

This Report summarizes the results of the activities of the LHC Higgs Cross Section Working
Group in the period 2014–2016. The main goal of the working group was to present the state …

A bstract We discuss the theoretical bases that underpin the automation of the computations
of tree-level and next-to-leading order cross sections, of their matching to parton shower …

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 …

We present an updated set of parameters for the PYTHIA 8 event generator. We reevaluate
the constraints imposed by LEP and SLD on hadronization, in particular with regard to heavy …

A bstract We present a new model for the hadronisation of multi-parton systems, in which
colour correlations beyond leading NC are allowed to influence the formation of confining …
