Search for new phenomena with top-quark pairs and large missing transverse momentum using 140 fb −1 of pp collision data at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics
A search is conducted for new phenomena in events with a top quark pair and large missing transverse momentum, where the top quark pair is reconstructed in final states with one isolated electron or muon and multiple jets.

Experimental validation of Geant4 nuclear interaction models in dose calculations of therapeutic carbon ion beams

open access: yesMedical Physics, Volume 52, Issue 7, July 2025.
Abstract Background The choice of nuclear interaction models in Monte Carlo simulations affects the dose calculation accuracy for light ion beam therapy. Purpose This study aimed to evaluate the dose calculation accuracy and simulation time of three GATE‐RTiON/Geant4 physics lists for therapeutic carbon ion beams, assessing their suitability for ...

Electron and photon efficiencies in LHC Run 2 with the ATLAS experiment

open access: yesJournal of High Energy Physics
Precision measurements of electron reconstruction, identification, and isolation efficiencies and photon identification efficiencies are presented. They use the full Run 2 data sample collected by the ATLAS experiment in pp collisions at a centre-of-mass

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.

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 ...

Off-Shell Effects for Single Top-Quark Production Processes at Hadron Colliders [PDF]

open access: yes, 2011
We present a calculation of s- and t-channel single top-quark production and decay at next-to-leading order in QCD for the Tevatron and for the LHC. The calculation includes the off-shell effects of the intermediate top-quark and the non-factorisable ...

Observation of electroweak production of W + W − in association with jets in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics
A measurement of the production of W bosons with opposite electric charges in association with two jets is presented based on 140 fb −1 of data collected by the ATLAS detector in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV.

Hadron -hadron scattering in lattice quantum chromodynamics

open access: yes, 2009
Hadron-hadron and multi-hadron scattering calculations in fully dynamical, mixed-action Lattice Quantum Chromodynamics using the MILC gauge ensembles in a non-perturbative simulation are discussed. In particular, calculations of the pi+sum+, pi+xi 0, K+p,
