Search for the production of a Higgs boson in association with a single top quark in pp collisions at s = 13 $$ \sqrt{s}=13 $$ TeV with the ATLAS detector

open access: yesJournal of High Energy Physics
A search for the production of a Higgs boson in association with a single top quark, tH, is presented. The analysis uses proton-proton collision data corresponding to an integrated luminosity of 140 fb −1 at a centre-of-mass energy of 13 TeV, collected ...

Probing the Higgs boson CP properties in vector-boson fusion production in the H → τ + τ − channel with the ATLAS detector

open access: yesJournal of High Energy Physics
The CP properties of the Higgs boson are studied in the vector-boson fusion production mode. The analysis exploits the decay mode of the Higgs boson into two τ-leptons using 140 fb −1 of proton-proton collision data at s = 13 $$ \sqrt{s}=13 $$ TeV ...

Search for direct production of winos and higgsinos in events with two same-charge leptons or three leptons in pp collision data at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
A search for supersymmetry targeting the direct production of winos and higgsinos is conducted in final states with either two leptons (e or μ) with the same electric charge, or three leptons.

Factorization at higher twist in hadron-hadron scattering

open access: yesNuclear Physics B, 1984
Abstract We study one-loop soft gluon effects in a scalar quark QCD model of the Drell-Yan process. We find that factorization of the type suggested by Politzer holds at order m 2 / s , but fails at order m 4 / s 2 . We suggest that this pattern holds to higher orders, and that the non-factoring terms are not suppressed by form factors.

Field output correction factors using a scintillation detector

open access: yesMedical Physics, Volume 52, Issue 6, Page 4844-4861, June 2025.
Abstract Background As small radiation fields play an ever‐increasing role in radiation therapy, accurate dosimetry of these fields becomes critical to ensure high quality dose calculation and treatment optimization. Despite the availability of several small volume dose detectors, small field dosimetry remains challenging.

Total Hadronic Cross Sections via the Holographic Pomeron Exchange

open access: yes, 2019
The analysis on the hadron-hadron scattering at high energies in the framework of holographic QCD is presented. Combining the Pomeron exchange kernel and the hadron-Pomeron couplings which are obtained from the bottom-up AdS/QCD models, we calculate the ...

A comparative analysis of GEANT4, MCNP6 and FLUKA on proton‐induced gamma‐ray simulation

open access: yesMedical Physics, Volume 52, Issue 6, Page 4862-4870, June 2025.
Abstract Background Precise range verification is essential in proton therapy to minimize treatment margins due to the steep dose fall‐off of proton beams. The emission of secondary radiation from nuclear reactions between incident particles and tissues stands out as a promising method for range verification. Two prominent techniques are PET and Prompt

Measurement of t-channel production of single top quarks and antiquarks in pp collisions at 13 TeV using the full ATLAS Run 2 data sample

open access: yesJournal of High Energy Physics
The production of single top quarks and top antiquarks via the t-channel exchange of a virtual W boson is measured in proton-proton collisions at a centre-of-mass energy of 13 TeV at the LHC using 140 fb −1 of ATLAS data.

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 ...
