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

Two Micron‐Size Dark Dimensions

open access: yesFortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

GLUON BREMSTRAHLUNG EFFECTS IN LARGE p HADRON-HADRON SCATTERING [PDF]

open access: yesAIP Conference Proceedings, 1982
We consider effects of parton (primarily gluon) bremstrahlung in the initial and final states of high transverse momentum hadron‐hadron scattering. Monte Carlo calculations based on conventional QCD parton branching and scattering processes are presented. The calculations are carried only to the parton level in the final state.

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 ...

Search for direct production of electroweakinos in final states with one lepton, jets and missing transverse momentum in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
Searches for electroweak production of wino-like chargino pairs, χ ~ 1 + χ ~ 1 − $$ {\overset{\sim }{\chi}}_1^{+}{\overset{\sim }{\chi}}_1^{-} $$ , and of wino-like chargino and next-to-lightest neutralino, χ ~ 1 ± χ ~ 2 0 $$ {\overset{\sim }{\chi}}_1 ...

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 ...

Interplay among transversity induced asymmetries in hadron leptoproduction [PDF]

open access: yes, 2004
In the fragmentation of a transversely polarized quark several left-right asymmetries are possible for the hadrons in the jet. When only one unpolarized hadron is selected, it exhibits an azimuthal modulation known as Collins effect.

Search for supersymmetry using vector boson fusion signatures and missing transverse momentum in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics
This paper presents a search for supersymmetric particles in models with highly compressed mass spectra, in events consistent with being produced through vector boson fusion. The search uses 140 fb −1 of proton-proton collision data at s $$ \sqrt{s} $$ =

Hadron-Hadron interactions from Nf=2+1+1 lattice QCD: I=3/2 πK scattering length [PDF]

open access: yesPhysical Review D, 2018
In this paper we report on results for the s-wave scattering length of the $\pi$-$K$ system in the $I=3/2$ channel from $N_f=2+1+1$ Lattice QCD. The calculation is based on gauge configurations generated by the European Twisted Mass Collaboration with ...
