Upgrade of ATLAS Hadronic Tile Calorimeter for the High-Luminosity LHC

Instruments, 2022
The Tile Calorimeter (TileCal) is a sampling hadronic calorimeter covering the central region of the ATLAS experiment, with steel as the absorber and plastic scintillators as the active medium.

Galactic Cosmic Ray Ionization on Uranus; Geomagnetic Latitude Dependencies

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Galactic Cosmic Rays (GCRs) are a major source of atmospheric ionization, influencing ion abundance, aerosol formation, and electrical processes. GCR‐induced effects are expected to be more pronounced on Uranus than planets closer to the Sun for two reasons; reduced solar irradiance, and weaker solar modulation of incident GCR.

Latent Outlier Exposure in Real-Time Anomaly Detection at the Large Hadron Collider

Computers
We propose a novel approach to real-time anomaly detection at the Large Hadron Collider, aimed at enhancing the discovery potential for new fundamental phenomena in particle physics.

Weak-strong beam-beam simulations for the Large Hadron Collider

Physical Review Special Topics. Accelerators and Beams, 1999
A weak-strong simulation code is used to study the single-particle stability in the presence of triplet field errors, head-on collisions, and long-range beam-beam interactions at the Large Hadron Collider.

Coherent Photoproduction of Low-pT Charmonium in Peripheral Heavy Ion Collisions within the Color Dipole Model

Advances in High Energy Physics, 2022
We calculate the centrality dependence for coherent photoproduction of very low-pTJ/ψ at Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC) energies within the impact parameter-dependent saturated color dipole model.

Assessing the Usefulness of Assurance Cases: Experience With the Large Hadron Collider

Systems Engineering, Volume 29, Issue 1, Page 99-113, January 2026.
ABSTRACT Assurance cases (ACs) are structured arguments designed to show that a system is sufficiently reliable to function properly in its operational environment. They are mandated by safety standards and are largely used in industry to support risk management for systems; however, ACs often contain proprietary information and are not publicly ...

ATLAS search for new phenomena in dijet mass and angular distributions using pp collisions at √s=7 TeV [PDF]

, 2013
Mass and angular distributions of dijets produced in LHC proton-proton collisions at a centre-of-mass energy √s=7 TeV have been studied with the ATLAS detector using the full 2011 data set with an integrated luminosity of 4.8 fb−1. Dijet masses up to ~ 4.

Chromatic coupling correction in the Large Hadron Collider

Physical Review Special Topics. Accelerators and Beams, 2013
In this article we present the measurement and correction of the chromatic coupling in the LHC. The transverse coupling is calculated from turn-by-turn data, exciting the beam with an ac dipole.

Anatomy of inclusive tt‾W production at hadron colliders

Physics Letters B, 2020
In LHC searches for new and rare phenomena the top-associated channel pp→tt‾W±+X is a challenging background that multilepton analyses must overcome. Motivated by sustained measurements of enhanced rates of same-sign and multi-lepton final states, we ...

An Overview of Scale Invariance in Proton Structure With Holographic Insights

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.
The concept of self‐similarity in the internal structure of the proton, rooted in scale invariance and fractal geometry, provides an intriguing framework for understanding the behavior of parton distribution functions (PDFs), particularly in the small x region probed in deep inelastic scattering (DIS).
