Search for resonances decaying into top-quark pairs using fully hadronic decays in pp collisions with ATLAS at s√=7 TeV [PDF]

open access: yes, 2013
A search for resonances produced in 7 TeV proton-proton collisions and decaying into top-quark pairs is described. In this Letter events where the top-quark decay produces two massive jets with large transverse momenta recorded with the ATLAS detector at

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 ...

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-
