Jet substructure measurements at ALICE
Leticia Cunqueiro, for the ALICE Collaboration

The yields and fragmentation pattern of jets are modified by the dense medium created in heavy ion collisions relative to proton proton collisions. The main scope of the jet program in heavy ions is to address those modifications, relate them to specific aspects of the dynamics of the jet-medium interactions...

17. Modifications to Jet Spectra and Substructure in PbPb Collisions with CMS

Talk

Study of inclusive jet spectra and substructure are powerful tools to study modifications of the parton shower as it propagates through the hot and dense medium produced in PbPb collisions. The observed suppression of jet production and the modification to jet substructure results in strong constraints on jet quenching mechanisms in heavy ion collisions. Combining substructure measurements...

51. Comparison of jet mass in $pp$ and Pb+Pb collisions using ATLAS at $\sqrt{s_{NN}}$=5.02 TeV

Talk

The mass of inclusive jets in lead-lead and proton-proton collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV is reported using the ATLAS Run 2 data at the LHC. Jet substructure observables are of interest to access the internal structure of jets produced in proton-proton collisions. These observables are sensitive to the angular and momentum correlations of the jet fragments, and are thus...

59. Measuring jet substructure observables at the ATLAS Experiment

Jennifer Kathryn Roloff (Harvard University (US))

Talk

Jet substructure observables have significantly extended the search program for physics beyond the Standard Model at the Large Hadron Collider. The state-of-the-art tools have been motivated by theoretical calculations, but there has never been a direct comparison between data and calculations of jet substructure observables that are accurate beyond leading-logarithm approximation. Such...

26. Measurements using jet substructures for SM physics at CMS

Matthias Ulrich Mozer (KIT - Karlsruhe Institute of Technology (DE))

Talk

The talk will report on measurements using jet substructures for top-quark physics and other standard-model channels by the CMS collaboration

58. Measurements with highly boosted top quarks using the ATLAS detector

Walter Hopkins (University of Oregon (US))

Talk

The high energy of the LHC allows access to large numbers of high transverse momentum top quarks. Measurements of differential cross-sections in top quark pair production at 13 TeV with the ATLAS detector are presented. They are performed using the lepton+jets and all-hadronic final states. Jet substructure techniques are used to identify hadronically decaying top quarks. The measurements are...
