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

Why Do Minoritized Students Deploy More Than One Language During a Physics Inquiry?

open access: yesJournal of Research in Science Teaching, Volume 62, Issue 10, Page 2147-2168, December 2025.
ABSTRACT We present a study that documented the participation of two high school Arab students in Israel in an extended (2‐year) authentic physics inquiry that took place in a regional program located in a Hebrew‐speaking kibbutz high school. The students' first language is Arabic, but they are fluent in Hebrew, and their inquiry was mentored by a ...

Measuring transversity densities in singly polarized hadron-hadron and lepton-hadron collisions

open access: yes, 1993
We show how the transverse polarization of a quark initiating a jet can be probed by the azimuthal distribution of two hadrons (of large $z$) in the jet.

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.

Development and dosimetric verification of static SHArc: Step‐and‐shoot carbon ion arc therapy for LETd escalation in pancreatic tumors

open access: yesMedical Physics, Volume 52, Issue 10, October 2025.
Abstract Background Carbon ion radiotherapy (CIRT) offers higher linear energy transfer (LET) and superior relative biological effectiveness, making it a promising option for treating hypoxic, radioresistant tumors. Spot‐scanning Hadron Arc (SHArc) therapy enables dose‐averaged LET (LETd) escalation in the tumor but increases planning and setup ...

Parton Models and Deep Hadron‐Hadron Scattering [PDF]

open access: yesAIP Conference Proceedings, 1973
We review the recent applications of various parton models, to the problem of hadron‐hadron scattering at large momentum transfers. Models which allow direct parton‐parton interaction as well as those that do not are considered. Predictions for the structure of hadronic final states (whether or not transverse jets exist), associated multiplities, and ...

The Quest for the Quark‐Gluon Plasma From the Perspective of Dynamical Models of Relativistic Heavy‐Ion Collisions

open access: yesAstronomische Nachrichten, Volume 346, Issue 7-8, September 2025.
ABSTRACT The physics of heavy‐ion collisions is one of the most exciting and challenging directions of science for the last four decades. On the theoretical side one deals with a non‐abelian field theory, while on the experimental side today's largest accelerators are needed to enable these studies.

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.

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.

Azimuthal asymmetries of charged hadrons produced by high-energy muons scattered off longitudinally polarised deuterons [PDF]

open access: yes, 2010
Azimuthal asymmetries in semi-inclusive production of positive (h^+) and negative hadrons (h^-) have been measured by scattering 160 GeV muons off longitudinally polarised deuterons at CERN.
