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.

Production of light (anti)nuclei in pp collisions at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics, 2022
Understanding the production mechanism of light (anti)nuclei is one of the key challenges of nuclear physics and has important consequences for astrophysics, since it provides an input for indirect dark-matter searches in space. In this paper, the latest

Characteristics of an inelastic vertex from Hadron-Hadron scattering

open access: yesNuclear Physics B, 1973
Inelastic π−p events at 25 GeV/c are selected to enhance the likehood of single-particle fragmentation. The fragmentation vertex is studied as a function of momentum transfer, effective mass and multiplicity. The t-dependence of the inelastic vertex suggests a point-like interaction, and the triple Regge-formalism shows promise for describing the M ...

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.

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.

Spin effects in high energy hadron-hadron scattering

open access: yesZeitschrift f�r Physik C Particles and Fields, 1991
The spin-flip amplitudes of the meson-nucleon and nucleon-nucleon scattering are calculated in the framework of the dynamic model taking into account the interactions at large distances. The consideration of the strong form factors at the corresponding vertex and prea-symptotic contributions allowed us to describe correctly the differential cross ...

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 ...

Search for a CP-odd Higgs boson decaying into a heavy CP-even Higgs boson and a Z boson in the ℓ + ℓ − t t ¯ $$ {\ell}^{+}{\ell}^{-}t\overline{t} $$ and ν ν ¯ b b ¯ $$ \nu \overline{\nu}b\overline{b} $$ final states using 140 fb −1 of data collected with the ATLAS detector

open access: yesJournal of High Energy Physics
A search for a heavy CP-odd Higgs boson, A, decaying into a Z boson and a heavy CP-even Higgs boson, H, is presented. It uses the full LHC Run 2 dataset of pp collisions at s $$ \sqrt{s} $$ = 13 TeV collected with the ATLAS detector, corresponding to an ...
