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 …

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 …

We introduce a new jet shape—N-subjettiness—designed to identify boosted hadronically-
decaying objects like electroweak bosons and top quarks. Combined with a jet invariant …

A bstract We show how generalized energy correlation functions can be used as a powerful
probe of jet substructure. These correlation functions are based on the energies and pair …

The series Lecture Notes in Physics (LNP), founded in 1969, reports new developments in
physics research and teaching-quickly and informally, but with a high quality and the explicit …

Jet substructure observables have significantly extended the search program for physics
beyond the standard model at the Large Hadron Collider. The state-of-the-art tools have …

A bstract In this work we perform the first ever calculation of jet event shapes at hadron
colliders at next-to-next-to leading order (NNLO) in QCD. The inclusion of higher order …

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 …
