Evolution variable dependence of jet substructure [PDF]

open access: yes, 2015
Studies on jet substructure have evolved significantly in recent years. Jet substructure is essentially determined by QCD radiations and non-perturbative effects.

Hadronic calorimeter shower size: Challenges and opportunities for jet substructure in the superboosted regime

open access: yesPhysics Letters B, 2016
Hadrons have finite interaction size with dense material, a basic feature common to known forms of hadronic calorimeters (HCAL). We argue that substructure variables cannot use HCAL information to access the microscopic nature of jets much narrower than ...

Unbinned deep learning jet substructure measurement in high Q2 ep collisions at HERA

open access: yesPhysics Letters B, 2023
The radiation pattern within high energy quark- and gluon-initiated jets (jet substructure) is used extensively as a precision probe of the strong force as well as an environment for optimizing event generators with numerous applications in high energy ...

Substructure of jets at HERA [PDF]

open access: yes, 2001
The substructure of jets produced in an exclusive and a charm-induced dijet sample in photoproduction and in charged and neutral current interactions has been studied with the ZEUS detector at HERA. Jets were identified using the longitudinally invariant

Modification of jet substructure in heavy ion collisions as a probe of the resolution length of quark-gluon plasma

open access: yesJournal of High Energy Physics, 2020
We present an analysis of the role that the quark-gluon plasma (QGP) resolution length, the minimal distance by which two nearby colored charges in a jet must be separated such that they engage with the plasma independently, plays in understanding the ...

Jet mass and substructure of inclusive jets in √s = 7 TeV pp collisions with the ATLAS experiment [PDF]

open access: yes, 2012
Recent studies have highlighted the potential of jet substructure techniques to identify the hadronic decays of boosted heavy particles. These studies all rely upon the assumption that the internal substructure of jets generated by QCD radiation is well ...

Systematic quark/gluon identification with ratios of likelihoods

open access: yesJournal of High Energy Physics, 2022
Discriminating between quark- and gluon-initiated jets has long been a central focus of jet substructure, leading to the introduction of numerous observables and calculations to high perturbative accuracy.

Boosted Jet Tagging with Jet-Images and Deep Neural Networks

open access: yesEPJ Web of Conferences, 2016
Building on the jet-image based representation of high energy jets, we develop computer vision based techniques for jet tagging through the use of deep neural networks.

Extraction of jet-medium interaction details through jet substructure for inclusive and gamma-tagged jets [PDF]

open access: yesEPJ Web of Conferences
We present a comprehensive study of jet substructure modifications in high-energy heavy-ion collisions using both inclusive jets and γ-tagged jets, based on a multi-stage jet evolution model within the Monte Carlo framework JETSCAPE.
