Vector boson tagged jets and jet substructure [PDF]

open access: yesEPJ Web of Conferences, 2018
In these proceedings, we report on recent results related to vector boson-tagged jet production in heavy ion collisions and the related modification of jet substructure, such as jet shapes and jet momentum sharing distributions.

Study of quark and gluon jet substructure in Z+jet and dijet events from pp collisions

open access: yesJournal of High Energy Physics, 2022
Measurements of jet substructure describing the composition of quark- and gluon-initiated jets are presented. Proton-proton (pp) collision data at s $$ \sqrt{s} $$ = 13 TeV collected with the CMS detector are used, corresponding to an integrated ...

Disentangling jet modification in jet simulations and in Z+jet data

open access: yesJournal of High Energy Physics, 2022
The selection of jets in heavy-ion collisions based on their p T after jet quenching is known to bias towards jets that lost little energy in the quark-gluon plasma.

Exploring jet substructure in semi-visible jets

open access: yesSciPost Physics, 2021
Semi-visible jets arise in strongly interacting dark sectors, where parton evolution includes dark sector emissions, resulting in jets overlapping with missing transverse momentum.

Learning to identify semi-visible jets

open access: yesJournal of High Energy Physics, 2022
We train a network to identify jets with fractional dark decay (semi-visible jets) using the pattern of their low-level jet constituents, and explore the nature of the information used by the network by mapping it to a space of jet substructure ...

Reconstructing boosted Higgs jets from event image segmentation

open access: yesJournal of High Energy Physics, 2021
Based on the jet image approach, which treats the energy deposition in each calorimeter cell as the pixel intensity, the Convolutional neural network (CNN) method has been found to achieve a sizable improvement in jet tagging compared to the traditional ...

Measurements of jet substructure and jet fragmentation using the ATLAS detector

open access: yesSciPost Physics Proceedings, 2022
Measurements of the internal properties of jets at the LHC interaction scale allow QCD to be studied in a new energy regime. In this talk, we discuss recent measurements of jet substructure and jet fragmentation, which were performed using data collected

Recent progress on jet substructure theory [PDF]

open access: yesEPJ Web of Conferences, 2020
In these proceedings, we review recent theoretical progress on jet substructure at the colliders. Focusing on two observables – jet mass and groomed jet radius, we perform theoretical computations for jets measured in the single inclusive jet production ...

Overview of jet physics results from ALICE [PDF]

open access: yesEPJ Web of Conferences, 2020
Recent results from jet shower-shape and substructure analyses done by the ALICE collaboration in central Pb–Pb collisions at √sNN = 2.76 TeV and in pp collisions at √s = 7 TeV are reviewed.

Identifying quenched jets in heavy ion collisions with machine learning

open access: yesJournal of High Energy Physics, 2023
Measurements of jet substructure in ultra-relativistic heavy ion collisions suggest that the jet showering process is modified by the interaction with the quark-gluon plasma. Modifications of the hard substructure of jets can be explored with modern data-
