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

Inclusive-photon production and its dependence on photon isolation in pp collisions at s $$ \sqrt{s} $$ = 13 TeV using 139 fb −1 of ATLAS data

open access: yesJournal of High Energy Physics, 2023
Measurements of differential cross sections are presented for inclusive isolated-photon production in pp collisions at a centre-of-mass energy of 13 TeV provided by the LHC and using 139 fb −1 of data recorded by the ATLAS experiment.

Monte Carlo study on fetal dose assessment for carbon beam craniospinal irradiation during pregnancy

open access: yesMedical Physics, Volume 53, Issue 3, March 2026.
Abstract Background Radiotherapy may be suggested for pregnant cancer patients when treatment cannot be delayed, with careful targeting to minimize fetal dose. Considering that a successful case for a pregnant patient treated with proton beam craniospinal irradiation (CSI) was reported, carbon therapy can be also considered applicable for the CSI ...

Search for Higgs boson decays into a pair of pseudoscalar particles in the γγτ had τ had final state using pp collisions at s $$ \sqrt{\textrm{s}} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics
A search for exotic decays of the 125 GeV Higgs boson into a pair of new spin-0 particles, H → aa, where one decays into a photon pair and the other into a τ-lepton pair, is presented.

Inclusive and multiplicity dependent production of electrons from heavy-flavour hadron decays in pp and p-Pb collisions

open access: yesJournal of High Energy Physics, 2023
Measurements of the production of electrons from heavy-flavour hadron decays in pp collisions at s $$ \sqrt{s} $$ = 13 TeV at midrapidity with the ALICE detector are presented down to a transverse momentum (p T) of 0.2 GeV/c and up to p T = 35 GeV/c ...

Galactic Cosmic Ray Ionization on Uranus; Geomagnetic Latitude Dependencies

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Galactic Cosmic Rays (GCRs) are a major source of atmospheric ionization, influencing ion abundance, aerosol formation, and electrical processes. GCR‐induced effects are expected to be more pronounced on Uranus than planets closer to the Sun for two reasons; reduced solar irradiance, and weaker solar modulation of incident GCR.

Beyond the black disk limit: from shadow to antishadow scattering mode

open access: yes, 1998
New mode in the hadron scattering is predicted to appear at the energies beyond $\sqrt{s}\simeq 2$ TeV: the antishadow scattering mode and the experiments at LHC and VLHC in hadronic reactions will be able to reveal it.

Inclusive hadron-hadron scattering in the Feynman gauge

open access: yesNuclear Physics B, 1985
Abstract We analyze the structure of high-energy inclusive hadron-hadron scattering in the Feynman gauge. We show that final-state interactions cancel on a graph-by-graph basis after a sum over final states. We go on to show that the leading high-energy behavior of disconnected parton scatterings in the Feynman gauge is the same as in physical gauges,

Quantum GraviElectro Dynamics

open access: yesAnnalen der Physik, Volume 538, Issue 1, January 2026.
The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,

k_T factorization is violated in production of high-transverse-momentum particles in hadron-hadron collisions

open access: yes, 2007
We show that hard-scattering factorization is violated in the production of high-p_T hadrons in hadron-hadron collisions, in the case that the hadrons are back-to-back, so that k_T factorization is to be used.
