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.

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.

Measurement of b jet shapes in proton-proton collisions at s $$ \sqrt{s} $$ = 5.02 TeV

open access: yesJournal of High Energy Physics, 2021
We present the first study of charged-hadron production associated with jets originating from b quarks in proton-proton collisions at a center-of-mass energy of 5.02 TeV.

Going off topics to demix quark and gluon jets in α S extractions

open access: yesJournal of High Energy Physics, 2023
Quantum chromodynamics is the theory of the strong interaction between quarks and gluons; the coupling strength of the interaction, α S , is the least precisely-known of all interactions in nature.

Jet Substructure Measurements with ALICE

open access: yesPhysics of Particles and Nuclei, 2023
A selection of new jet substructure measurements are reported from the ALICE experiment at the CERN LHC in both proton-proton and heavy-ion collisions. These include the first fully corrected inclusive measurements of the groomed jet momentum fraction and the groomed jet radius, as well as the $N$-subjettiness distribution and the fragmentation ...

Measurement of substructure-dependent suppression of large-radius jets with charged particles in Pb+Pb collisions with ATLAS

open access: yesPhysics Letters B
Measurements of jet substructure in Pb+Pb collisions provide key insights into the mechanism of jet quenching in the hot and dense QCD medium created in these collisions.This Letter presents a measurement of the suppression of large-radius jets with a ...
