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 …

The study of the internal structure of hadronic jets has become in recent years a very active
area of research in particle physics. Jet substructure techniques are increasingly used in …

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 …

A bstract We introduce a new jet substructure technique called “soft drop declustering”,
which recursively removes soft wide-angle radiation from a jet. The soft drop algorithm …

This Report summarizes the results of the activities in 2012 and the first half of 2013 of the
LHC Higgs Cross Section Working Group. The main goal of the working group was to …

A bstract We present first analytic, resummed calculations of the rates at which wide-spread
jet substructure tools tag QCD jets. As well as considering trimming, pruning and the mass …

The accuracy of parton-shower simulations is often a limiting factor in the interpretation of
data from high-energy colliders. We present the first formulation of parton showers with …

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 …

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 …
