The ALFA Roman Pot Detectors of ATLAS
S. Abdel Khalek, B. Allongue, F. Anghinolfi +42
The ATLAS Roman Pot system is designed to determine the total proton-proton cross-section as well as the luminosity at the Large Hadron Collider (LHC) by measuring elastic proton s…
On the Space-Time Symmetries of Non-Commutative Gauge Theories
A. Iorio, T. Sykora
We study the space-time symmetries and transformation properties of the non-commutative U(1) gauge theory, by using Noether charges. We carry out our analysis by keeping an open vi…
Machine Learning-Assisted Measurement of Lepton-Jet Azimuthal Angular Asymmetries in Deep-Inelastic Scattering at HERA
The H1 collaboration, V. Andreev, M. Arratia +141
In deep-inelastic positron-proton scattering, the lepton-jet azimuthal angular asymmetry is measured using data collected with the H1 detector at HERA. When the average transverse…
Beam tests of an integrated prototype of the ATLAS Forward Proton detector
J. Lange, L. Adamczyk, G. Avoni +24
The ATLAS Forward Proton (AFP) detector is intended to measure protons scattered at small angles from the ATLAS interaction point. To this end, a combination of 3D Silicon pixel tr…
Expected Performance of the ATLAS Experiment - Detector, Trigger and Physics
The ATLAS Collaboration, G. Aad, E. Abat +2604
A detailed study is presented of the expected performance of the ATLAS detector. The reconstruction of tracks, leptons, photons, missing energy and jets is investigated, together w…
ePIC Early Science Report
D. Abbott, N. Abdelrahman, S. Abhijit +781
This Early Science Report from the ePIC Collaboration outlines the compelling physics program achievable during the first years of operation of the Electron-Ion Collider (EIC), pri…
Covariant Schwinger terms
C. Adam, C. Ekstrand, T. Sykora
There exist two versions of the covariant Schwinger term in the literature. They only differ by a sign. However, we shall show that this is an essential difference. We shall carefu…
Measurement of lepton-jet correlation in deep-inelastic scattering with the H1 detector using machine learning for unfolding
H1 Collaboration, V. Andreev, M. Arratia +142
The first measurement of lepton-jet momentum imbalance and azimuthal correlation in lepton-proton scattering at high momentum transfer is presented. These data, taken with the H1 d…

The H1 Collaboration reports the first measurement of the 1-jettiness event shape observable in neutral-current deep-inelastic electron-proton scattering (DIS). The observ…
Impact of jet-production data on the next-to-next-to-leading-order determination of HERAPDF2.0 parton distributions
H1, ZEUS Collaborations, : +234
The HERAPDF2.0 ensemble of parton distribution functions (PDFs) was introduced in 2015. The final stage is presented, a next-to-next-to-leading-order (NNLO) analysis of the HERA da…
Observation and differential cross section measurement of neutral current DIS events with an empty hemisphere in the Breit frame
The H1 collaboration, V. Andreev, M. Arratia +146
The Breit frame provides a natural frame to analyze lepton-proton scattering events. In this reference frame, the parton model hard interactions between a quark and an exchanged bo…
