Quarks and gluons in the Lund plane

open access: yesJournal of High Energy Physics, 2022
Discriminating quark and gluon jets is a long-standing topic in collider phenomenology. In this paper, we address this question using the Lund jet plane substructure technique introduced in recent years. We present two complementary approaches: one where

Energy-energy correlators in p-Pb collisions at ALICE [PDF]

open access: yesEPJ Web of Conferences
Jet substructure is a powerful tool for testing QCD in elementary particle collisions. The two-point energy-energy correlator (EEC), defined as the energy-weighted cross section of particle pairs inside jets, is a novel jet-substructure observable ...

QCD resummation for groomed jet observables at NNLL+NLO

open access: yesJournal of High Energy Physics, 2023
We use a direct QCD approach to carry out the next-to-next-to-leading logarithmic (NNLL) resummation for observables groomed with the modified mass-drop tagger (Soft Drop β = 0).

Lund and Cambridge multiplicities for precision physics

open access: yesJournal of High Energy Physics, 2022
We revisit the calculation of the average jet multiplicity in high-energy collisions. First, we introduce a new definition of (sub)jet multiplicity based on Lund declusterings obtained using the Cambridge jet algorithm.

The simplicial substructure of jets

open access: yes, 2023
In this work, we construct a new data type for hadronic jets in which the traditional point-cloud representation is transformed into a simplicial complex consisting of vertices, or 0-simplexes. An angular resolution scale, $r$, is then drawn about each vertex, forming balls about hadrons.

Jet fragmentation function and groomed substructure of bottom quark jets in proton-proton collisions at 5.02 TeV

open access: yesJournal of High Energy Physics
A measurement of the substructure of bottom quark jets (b jets) in proton-proton (pp) collisions is presented. The measurement uses data collected in pp collisions at s = 5.02 $$ \sqrt{s}=5.02 $$ TeV, with a low number of simultaneous interactions per ...

Probing jet hadrochemistry modification with measurements of π, K, and p in jets and the underlying event in pp and Pb–Pb collisions at √sNN = 5.02 TeV [PDF]

open access: yesEPJ Web of Conferences
Measurements of jet substructure observables in heavy-ion (HI) collisions provide powerful constraints on the microscopic mechanisms of interactions between energetic partons and the quark–gluon plasma (QGP).

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

open access: yesFEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

ATLAS Jet Reconstruction, Calibration, and Tagging of Lorentzboosted Objects

open access: yesEPJ Web of Conferences, 2018
Jet reconstruction in the ATLAS detector takes multiple forms, as motivated by the intended usage of the jet. Different jet definitions are used in particular for the study of QCD jets and jets containing the hadronic decay of boosted massive particles ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

open access: yesFEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...
