High Energy Hadron-Nucleus Cross Sections and Their Extrapolation to Cosmic Ray Energies [PDF]

open access: yes, 1995
Old models of the scattering of composite systems based on the Glauber model of multiple diffraction are applied to hadron-nucleus scattering. We obtain an excellent fit with only two free parameters to the highest energy hadron-nucleus data available ...

Triggering soft bombs at the LHC

open access: yesJournal of High Energy Physics, 2017
Very high multiplicity, spherically-symmetric distributions of soft particles, with p T ∼ few×100 MeV, may be a signature of strongly-coupled hidden valleys that exhibit long, efficient showering windows.

Measurements of W + W − + ≥ 1 jet production cross-sections in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2021
Fiducial and differential cross-section measurements of W + W − production in association with at least one hadronic jet are presented. These measurements are sensitive to the properties of electroweak-boson self-interactions and provide a test of ...

The Quark and Gluon Structure of the Proton

open access: yes, 2012
In this article we present a review of the structure of the proton and the current status of our knowledge of the parton distribution functions (PDFs).

Bose-Einstein correlations in hadron-pairs from lepto-production on nuclei ranging from hydrogen to xenon [PDF]

open access: yes, 2015
Bose-Einstein correlations of like-sign charged hadrons produced in deep-inelastic electron and positron scattering are studied in the HERMES experiment using nuclear targets of $^1$H, $^2$H, $^3$He, $^4$He, N, Ne, Kr, and Xe. A Gaussian approach is used

Measurement of jet-substructure observables in top quark, W boson and light jet production in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2019
A measurement of jet substructure observables is presented using data collected in 2016 by the ATLAS experiment at the LHC with proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV.

Puzzles in Hadronic Physics and Novel Quantum Chromodynamics Phenomenology [PDF]

open access: yes, 2012
We review some outstanding puzzles and experimental anomalies in hadron physics that appear to challenge conventional wisdom and, in some cases, the foundations of QCD.

Angular analysis of B d 0  → K ∗ μ + μ − decays in pp collisions at s = 8 $$ \sqrt{s}=8 $$ TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2018
An angular analysis of the decay B d 0  → K ∗ μ + μ − is presented, based on proton-proton collision data recorded by the ATLAS experiment at the LHC. The study is using 20.3 fb−1 of integrated luminosity collected during 2012 at centre-of-mass energy of

B Production Asymmetries in Perturbative QCD [PDF]

open access: yes, 2001
This paper explores a new mechanism for B production in which a b quark combines with a light parton from the hard-scattering process before hadronizing into the B hadron. This recombination mechanism can be calculated within perturbative QCD up to a few

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

open access: yesFortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.
