Journal of High Energy Physics, 2023 We compute the average Lund multiplicity of high-energy QCD jets. This extends an earlier calculation, done for event-wide multiplicity in e + e − collisions [1], to the large energy range available at the LHC.

Convolved substructure: analytically decorrelating jet substructure observables [PDF]
Journal of High Energy Physics, 2018 Abstract A number of recent applications of jet substructure, in particular searches for light new particles, require substructure observables that are decorrelated with the jet mass. In this paper we introduce the Convolved SubStructure (CSS) approach, which uses a theoretical understanding of the observable to decorrelate the ...

Energy correlation functions for jet substructure [PDF]
Journal of High Energy Physics, 2013 Abstract We show how generalized energy correlation functions can be used as a powerful probe of jet substructure. These correlation functions are based on the energies and pair-wise angles of particles within a jet, with (N + 1)-point correlators sensitive to N-prong substructure.

Composite octet searches with jet substructure [PDF]
Journal of High Energy Physics, 2012 Abstract Many new physics models with strongly interacting sectors predict a mass hierarchy between the lightest vector meson and the lightest pseudoscalar mesons. We examine the power of jet substructure tools to extend the 7 TeV LHC sensitivity to these new states for the case of QCD octet mesons, considering both two gluon and ...

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

Jet and Jet Substructure: ALICE Results
Acta Physica Polonica B Proceedings SupplementJets and their substructure in pp collisions offer a unique opportunity to probe various aspects of quantum chromodynamics (QCD), ranging from perturbative QCD (pQCD) tests to studies of non-perturbative phenomena such as hadronization. They also probe the transition between perturbative and non-perturbative regimes. In heavy-ion collisions, jets serve

Heavy flavour jet substructure
Journal of High Energy PhysicsA bstract We present a comprehensive study of energy correlation functions and jet angularities for heavy-flavour QCD jets. In particular, we discuss the possibility of using these observables to expose the dead cone effect, i.e.

, 2017 We introduce a novel jet substructure method which exploits the variation of observables with respect to a sampling of phase-space boundaries quantified by the variability. We apply this technique to identify boosted W boson and top quark jets using telescoping subjets which utilizes information coming from subjet topology and that coming from subjet ...

Studies of the internal properties of jets and jet substructure with the ATLAS Detector
, 2011 The internal structure of jets produced in pp collisions at the LHC is measured using the ATLAS detector in an inclusive jet sample corresponding to 35pb-1 of pp collisions at sqrt(s) = 7 TeV.
