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 …

In this article, we review some of the complexities of jet algorithms and of the resultant
comparisons of data to theory. We review the extensive experience with jet measurements at …

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 …

The simulation software for the ATLAS Experiment at the Large Hadron Collider is being
used for large-scale production of events on the LHC Computing Grid. This simulation …

We present 9 new tunes of the p⊥-ordered shower and underlying-event model in Pythia
6.4. These “Perugia” tunes update and supersede the older “S0” family. The data sets used …

FastJet is a C++ package that provides a broad range of jet finding and analysis tools. It
includes efficient native implementations of all widely used 2→ 1 sequential recombination …

We describe the implementation details of the colour reconnection model in the event
generator Herwig++. We study the impact on final-state observables in detail and confirm the …

We provide ingredients and recipes for computing signals of TeV-scale Dark Matter
annihilations and decays in the Galaxy and beyond. For each DM channel, we present the …

In this paper the current release of the Monte Carlo event generator Sherpa, version 1.1, is
presented. Sherpa is a general-purpose tool for the simulation of particle collisions at high …

This is the manual and user guide for the Rivet system for the validation and tuning of Monte
Carlo event generators. As well as the core Rivet library, this manual describes the usage of …
