This report describes the physics case, the resulting detector requirements, and the evolving
detector concepts for the experimental program at the Electron-Ion Collider (EIC). The EIC …

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 …

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 detail a simulation of Higgs boson production via gluon fusion, accurate at next-
to-next-to-leading order in the strong coupling, including matching to a parton shower …

Parton showers are among the most widely used tools in collider physics. Despite their key
importance, none so far have been able to demonstrate accuracy beyond a basic level …

The successful operation of the Large Hadron Collider (LHC) and the excellent performance
of the ATLAS, CMS, LHCb and ALICE detectors in Run-1 and Run-2 with $ pp $ collisions at …
