Jet substructure measurements in pp collisions at $\sqrt{s}$ = 13 TeV with ALICE

open access: yes, 2019
We present a variety of jet substructure measurements performed in pp collisions at $\sqrt{s}$ = 13 TeV with the focus on the groomed jet momentum fraction $z_{\rm{g}}$ in a wide range of $p_{\rm{T}}$ between 20 and 200 GeV/$c$ and jet resolution $0.2 ...

Jet Substructure by Accident [PDF]

open access: yes, 2013
We propose a new search strategy for high-multiplicity hadronic final states. When new particles are produced at threshold, the distribution of their decay products is approximately isotropic.

Jet Substructure Without Trees [PDF]

open access: yes, 2011
We present an alternative approach to identifying and characterizing jet substructure. An angular correlation function is introduced that can be used to extract angular and mass scales within a jet without reference to a clustering algorithm.

Azimuthal decorrelation between a jet and a Z boson at hadron colliders

open access: yesJournal of High Energy Physics, 2022
We revisit the azimuthal decorrelation δϕ between a jet and a Z boson produced at hadron colliders. Employing different recombination schemes for the jets leads to significantly different NLL-resummed predictions for the distribution of this quantity ...

Particle-level pileup subtraction for jets and jet shapes [PDF]

open access: yes, 2014
We present an extension to the jet area-based pileup subtraction for both jet kinematics and jet shapes. A particle-level approach is explored whereby the jet constituents are corrected or removed using an extension of the methods currently being ...

Jet substructure with analytical methods

open access: yes, 2013
We consider the mass distribution of QCD jets after the application of jet substructure methods, specifically the mass-drop tagger, pruning, trimming and their variants.

On the Topic of Jets: Disentangling Quarks and Gluons at Colliders [PDF]

open access: yes, 2018
We introduce jet topics: a framework to identify underlying classes of jets from collider data. Because of a close mathematical relationship between distributions of observables in jets and emergent themes in sets of documents, we can apply recent ...

First measurements of N-subjettiness in central Pb-Pb collisions at s NN $$ \sqrt{s_{\mathrm{NN}}} $$ = 2.76 TeV

open access: yesJournal of High Energy Physics, 2021
The ALICE Collaboration reports the first fully-corrected measurements of the N-subjettiness observable for track-based jets in heavy-ion collisions. This study is performed using data recorded in pp and Pb-Pb collisions at centre-of-mass energies of s $$

A method for correcting the substructure of multiprong jets using the Lund jet plane

open access: yesJournal of High Energy Physics
Many analyses at the CERN LHC exploit the substructure of jets to identify heavy resonances produced with high momenta that decay into multiple quarks and/or gluons.
