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 …

A bstract The past few years have seen a rapid development of machine-learning
algorithms. While surely augmenting performance, these complex tools are often treated as …

In this paper, we review recent theoretical progress and the latest experimental results in jet
substructure from the Tevatron and the LHC. We review the status of and outlook for …

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 …

Over the past decade, a large number of jet substructure observables have been proposed
in the literature, and explored at the LHC experiments. Such observables attempt to utilize …

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

This report of the BOOST2012 workshop presents the results of four working groups that
studied key aspects of jet substructure. We discuss the potential of first-principle QCD …

A bstract A number of recent applications of jet substructure, in particular searches for light
new particles, require substructure observables that are decorrelated with the jet mass. In …

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 …

A bstract We introduce a new class of event shapes to characterize the jet-like structure of an
event. Like traditional event shapes, our observables are infrared/collinear safe and involve …
