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.

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 vacuum structure in QCD and hadron-hadron scattering

open access: yesZeitschrift f�r Physik C: Particles and Fields, 1984
Standard ideas on the structure of the vacuum in QCD suggest it to be full of fluctuating color fields. We investigate the possible influence of the chromomagnetic vacuum fields on high energy hadron-hadron reactions. We suggest that high energy quarks traversing these fields will produce soft gluon and photon radiation analogous to synchrotron ...

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

open access: yesJournal of Research in Science Teaching, EarlyView.
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 ...

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

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.

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.

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.

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.

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 ...
