Measurement of the k t splitting scales in Z → ℓℓ events in pp collisions at s = 8 $$ \sqrt{s}=8 $$ TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2017
A measurement of the splitting scales occuring in the k t jet-clustering algorithm is presented for final states containing a Z boson. The measurement is done using 20.2 fb−1 of proton-proton collision data collected at a centre-of-mass energy of s = 8 $$

Search for new non-resonant phenomena in high-mass dilepton final states with the ATLAS detector

open access: yesJournal of High Energy Physics, 2020
A search for new physics with non-resonant signals in dielectron and dimuon final states in the mass range above 2 TeV is presented. This is the first search for non-resonant signals in dilepton final states at the LHC to use a background estimate from ...

A comparative analysis of GEANT4, MCNP6 and FLUKA on proton‐induced gamma‐ray simulation

open access: yesMedical Physics, EarlyView.
Abstract BackgroundPrecise 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.

J/ψ elliptic and triangular flow in Pb-Pb collisions at s NN $$ \sqrt{s_{\mathrm{NN}}} $$ = 5.02 TeV

open access: yesJournal of High Energy Physics, 2020
The inclusive J/ψ elliptic (v 2) and triangular (v 3) flow coefficients measured at forward rapidity (2.5 < y < 4) and the v 2 measured at midrapidity (|y| < 0.9) in Pb-Pb collisions at s NN $$ \sqrt{s_{\mathrm{NN}}} $$ = 5.02 TeV using the ALICE ...

Out‐of‐field neutron radiation from clinical proton, helium, carbon, and oxygen ion beams

open access: yesMedical Physics, EarlyView.
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 ...

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 ...

Measurement of the cross-section for producing a W boson in association with a single top quark in pp collisions at s=13 $$ \sqrt{s}=13 $$ TeV with ATLAS

open access: yesJournal of High Energy Physics, 2018
The inclusive cross-section for the associated production of a W boson and top quark is measured using data from proton-proton collisions at s=13 $$ \sqrt{s}=13 $$ TeV. The dataset corresponds to an integrated luminosity of 3.2 fb−1, and was collected in
