Resolving Boosted Jets with XCone [PDF]

, 2015
We show how the recently proposed XCone jet algorithm smoothly interpolates between resolved and boosted kinematics. When using standard jet algorithms to reconstruct the decays of hadronic resonances like top quarks and Higgs bosons, one typically needs

Computing N -subjettiness for boosted jets

Journal of High Energy Physics, 2018
Jet substructure tools have proven useful in a number of high-energy particle-physics studies. A particular case is the discrimination, or tagging, between a boosted jet originated from an electroweak boson (signal), and a standard QCD parton (background)

Lund multiplicity in QCD jets

Journal of High Energy Physics, 2023
We compute the average Lund multiplicity of high-energy QCD jets. This extends an earlier calculation, done for event-wide multiplicity in e + e − collisions [1], to the large energy range available at the LHC.

Jet Substructure Studies with CMS Open Data [PDF]

, 2017
We use public data from the CMS experiment to study the 2-prong substructure of jets. The CMS Open Data is based on 31.8/pb of 7 TeV proton-proton collisions recorded at the Large Hadron Collider in 2010, yielding a sample of 768,687 events containing a ...

ATLAS Jet Reconstruction, Calibration, and Tagging of Lorentzboosted Objects

EPJ Web of Conferences, 2018
Jet reconstruction in the ATLAS detector takes multiple forms, as motivated by the intended usage of the jet. Different jet definitions are used in particular for the study of QCD jets and jets containing the hadronic decay of boosted massive particles ...

Studies of the internal properties of jets and jet substructure with the ATLAS Detector

, 2011
The internal structure of jets produced in pp collisions at the LHC is measured using the ATLAS detector in an inclusive jet sample corresponding to 35pb-1 of pp collisions at sqrt(s) = 7 TeV.

Jet-Images: Computer Vision Inspired Techniques for Jet Tagging

, 2015
We introduce a novel approach to jet tagging and classification through the use of techniques inspired by computer vision. Drawing parallels to the problem of facial recognition in images, we define a jet-image using calorimeter towers as the elements of

Invariant representation driven neural classifier for anti-QCD jet tagging

Journal of High Energy Physics, 2022
We leverage representation learning and the inductive bias in neural-net-based Standard Model jet classification tasks, to detect non-QCD signal jets. In establishing the framework for classification-based anomaly detection in jet physics, we demonstrate

Structure of Fat Jets at the Tevatron and Beyond

, 2011
Boosted resonances is a highly probable and enthusiastic scenario in any process probing the electroweak scale. Such objects when decaying into jets can easily blend with the cornucopia of jets from hard relative light QCD states.

Identifying a new particle with jet substructures [PDF]

, 2016
We investigate a potential of measuring properties of a heavy resonance X, exploiting jet substructure techniques. Motivated by heavy higgs boson searches, we focus on the decays of X into a pair of (massive) electroweak gauge bosons.
