Hadron mass corrections in semi-inclusive deep-inelastic scattering

open access: yesJournal of High Energy Physics, 2015
The spin-dependent cross sections for semi-inclusive lepton-nucleon scattering are derived in the framework of collinear factorization, including the effects of masses of the target and produced hadron at finite momentum transfer squared Q^2.

Quark-hadron duality in electron scattering

open access: yesPhysics Reports, 2005
The duality between partonic and hadronic descriptions of physical phenomena is one of the most remarkable features of strong interaction physics. A classic example of this is in electron-nucleon scattering, in which low-energy cross sections, when ...

Out-of-field neutron radiation from clinical proton, helium, carbon, and oxygen ion beams. [PDF]

open access: yesMed Phys
Abstract Background In hadron therapy, out‐of‐field doses, which may in the long‐term cause secondary cancers, are mostly due to neutrons. Very recently, 4He and 16O beams have been added to protons and 12C ions for clinical therapy. Purpose The focus of this article is to compare secondary neutron doses produced by clinical protons, 4He, 12C, and 16O ...

Diffraction at HERA and the Confinement Problem [PDF]

open access: yes, 2000
We discuss HERA data on the high energy behavior of the total gamma*p cross section and on diffraction in deep inelastic scattering. We outline their novelty in comparison with diffraction in high energy hadron hadron scattering.

An Updated Description of Heavy-Hadron Interactions in Geant-4 [PDF]

open access: yes, 2009
Exotic stable massive particles (SMP) are proposed in a number of scenarios of physics beyond the Standard Model. It is important that LHC experiments are able both to detect and extract the quantum numbers of any SMP with masses around the TeV scale. To

Search for supersymmetry in events with b-tagged jets and missing transverse momentum in pp collisions at s=13 $$ \sqrt{s}=13 $$ TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2017
A search for the supersymmetric partners of the Standard Model bottom and top quarks is presented. The search uses 36.1 fb−1 of pp collision data at s=13 $$ \sqrt{s}=13 $$ TeV collected by the ATLAS experiment at the Large Hadron Collider.

Probing the W tb vertex structure in t-channel single-top-quark production and decay in pp collisions at s = 8 $$ \sqrt{s}=8 $$ TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2017
To probe the W tb vertex structure, top-quark and W -boson polarisation observables are measured from t-channel single-top-quark events produced in proton-proton collisions at a centre-of-mass energy of 8 TeV.

Matrix element regression with deep neural networks — Breaking the CPU barrier

open access: yesJournal of High Energy Physics, 2021
The Matrix Element Method (MEM) is a powerful method to extract information from measured events at collider experiments. Compared to multivariate techniques built on large sets of experimental data, the MEM does not rely on an examples-based learning ...

Measuring Parton Densities in the Pomeron [PDF]

open access: yes, 1994
We present a program to measure the parton densities in the pomeron using diffractive deep inelastic scattering and diffractive photoproduction, and to test the resulting parton densities by applying them to other processes such as the diffractive ...
