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 ...

A comparative analysis of GEANT4, MCNP6 and FLUKA on proton-induced gamma-ray simulation. [PDF]

open access: yesMed Phys
Abstract Background Precise range verification is essential in proton therapy to minimize treatment margins due to the steep dose fall‐off of proton beams. The emission of secondary radiation from nuclear reactions between incident particles and tissues stands out as a promising method for range verification. Two prominent techniques are PET and Prompt

Bose-Einstein correlations of charged hadrons in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics, 2020
Bose-Einstein correlations of charged hadrons are measured over a broad multiplicity range, from a few particles up to about 250 reconstructed charged hadrons in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV.

Structure functions at large x [PDF]

open access: yes, 2001
Structure function data together with other measurements from fixed-target deep inelastic scattering and hadron-hadron collider experiments which contribute to our knowledge of the parton density functions are reviewed.

Results of a Geant4 benchmarking study for bio-medical applications, performed with the G4-Med system. [PDF]

open access: yesMed Phys
Abstract Background Geant4, a Monte Carlo Simulation Toolkit extensively used in bio‐medical physics, is in continuous evolution to include newest research findings to improve its accuracy and to respond to the evolving needs of a very diverse user community.

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

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 ...

Measurement of the production of charm jets tagged with D0 mesons in pp collisions at s = 7 $$ \sqrt{\mathrm{s}}=7 $$ TeV

open access: yesJournal of High Energy Physics, 2019
The production of charm jets in proton-proton collisions at a center-of-mass energy of s = 7 $$ \sqrt{s}=7 $$ TeV was measured with the ALICE detector at the CERN Large Hadron Collider.

Primordial nucleosynthesis and hadronic decay of a massive particle with a relatively short lifetime [PDF]

open access: yes, 2001
In this paper we consider the effects on big bang nucleosynthesis (BBN) of the hadronic decay of a long-lived massive particle. If high-energy hadrons are emitted near the BBN epoch ($t \sim 10^{-2}$ -- $10^2 \sec$), they extraordinarily inter-convert ...

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.
