Differential cross sections for high energy elastic hadron-hadron scattering in nonperturbative QCD

open access: yes, 1998
Total and differential cross sections for high energy and small momentum transfer elastic hadron-hadron scattering are studied in QCD using a functional integral approach.

In vivo dosimetry for proton therapy: A Monte Carlo study of the Gadolinium spectral response throughout the course of treatment

open access: yesMedical Physics, Volume 52, Issue 4, Page 2412-2424, April 2025.
Abstract Background In proton radiotherapy, the steep dose deposition profile near the end of the proton's track, the Bragg peak, ensures a more conformed deposition of dose to the tumor region when compared with conventional radiotherapy while reducing the probability of normal tissue complications.

Performance of the missing transverse momentum triggers for the ATLAS detector during Run-2 data taking

open access: yesJournal of High Energy Physics, 2020
The factor of four increase in the LHC luminosity, from 0.5 × 1034 cm −2s −1 to 2.0 × 1034cm −2s −1, and the corresponding increase in pile-up collisions during the 2015–2018 data-taking period, presented a challenge for the ATLAS trigger, particularly ...

Electron beam monitoring of a modified conventional medical accelerator with a portable current transformer system traceable to primary electrical standards

open access: yesMedical Physics, Volume 52, Issue 4, Page 2581-2592, April 2025.
Abstract Background Ultra‐high dose rate radiotherapy (UHDR) delivers therapeutic doses at rates >40 Gy/s in a fraction of a second, aiming to enhance the therapeutic ratio through the FLASH effect. The substantial increase in UHDR beam current poses serious challenges for conventional active dosimeters.

Ferrites with a Minimized Secondary Electron Yield

open access: yesAdvanced Science, Volume 12, Issue 10, March 13, 2025.
Ferrites are a key material in particle accelerators and space science, exposing them to high energy electrons and leading to multipacting, charging and electron cloud formation. Laser engineered surface structures are shown to dramatically reduce the secondary electron yield of ferrite eliminating these issues.

Behavior of the Hadron Potential at Large Distances and Properties of the Hadron Spin-flip Amplitude

open access: yes, 2001
The impact of the form of the hadron potential at large distances on the behaviour of the hadron spin-flip amplitude at small angles is examined. The $t$-dependence of the spin-flip amplitude of high energy hadron elastic scattering is analyzed under ...

Exploring Dark Photon Production and Kinetic Mixing Constraints in Heavy‐Ion Collisions

open access: yesAstronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.
ABSTRACT Vector U‐bosons, often referred to as “dark photons,” are potential candidates for mediating dark matter interactions. In this study, we outline a procedure to derive theoretical constraints on the upper bound of the kinetic mixing parameter ϵ2MU$$ {\upvarepsilon}^2\left({M}_U\right) $$ using dilepton data from heavy‐ion from SIS to RHIC ...

Differential cross-section measurements of the production of four charged leptons in association with two jets using the ATLAS detector

open access: yesJournal of High Energy Physics
Differential cross-sections are measured for the production of four charged leptons in association with two jets. These measurements are sensitive to final states in which the jets are produced via the strong interaction as well as to the purely ...

Hadron mass corrections in semi-inclusive deep-inelastic scattering

open access: yes, 2015
The spin-dependent cross sections for semi-inclusive lepton-nucleon scattering are derived in the framework of collinear factorization, including the effects of masses of the target and produced hadron at finite momentum transfer squared Q^2.
