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

open access: yesMedical Physics, Volume 52, Issue 6, Page 4862-4870, June 2025.
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

Search for a new heavy scalar particle decaying into a Higgs boson and a new scalar singlet in final states with one or two light leptons and a pair of τ-leptons with the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
A search for a new heavy scalar particle X decaying into a Standard Model (SM) Higgs boson and a new singlet scalar particle S is presented. The search uses a proton-proton (pp) collision data sample with an integrated luminosity of 140 fb −1 recorded at

Hadron-Hadron Scattering in the Nonrelativistic Quark Model

open access: yes, 2001
In this HADRON2001 contribution we summarize the status of our quark-model calculations of hadron-hadron scattering amplitudes in annihilation-free channels.

Hadron-Hadron Interactions

open access: yes, 1994
The present status of the chiral approach to the $NN$ interaction as proposed by Weinberg is discussed. The important role of correlation effects and explicit vector meson ($ $, $ $) exchange in the dynamics of baryon-baryon interactions is demonstrated.

High energy hadron-hadron collisions [PDF]

open access: yes, 1990
Results of a study on high energy collision with the geometrical model are summarized in three parts: (i) the elastic hadron-hadron collision, (ii) the inelastic hadron-hadron collision, and (iii) the e{sup +}e{sup {minus}} annihilation. For elastic collisions, a simple expression for the proton matter distribution is proposed which fits well the ...

Hadron Freeze-Out and Qgp Hadronization [PDF]

open access: yes, 1999
Abundances and $m_\bot$-spectra of strange and other hadronic particles emanating from central 158-200 A GeV reactions between nuclei are found to originate from a thermally equilibrated, deconfined source in chemical non-equilibrium. Physical freeze-out parameters and physical conditions (pressure, specific energy, entropy, and strangeness) are ...

Photonic Integrated Circuits for Optical Satellite Links: A Review of the Technology Status and Space Effects

open access: yesInternational Journal of Satellite Communications and Networking, Volume 43, Issue 3, Page 210-228, May/June 2025.
ABSTRACT Optical satellite communications provide high‐data rates with compact and power efficient payloads that can solve the bottlenecks of RF technologies. Photonic integrated circuits have the potential to reduce the cost, size, weight, and power consumption of satellite laser communications terminals, by integrating all the required photonic ...

Quark-Hadron Duality and Effective Continuum Thresholds in Dispersive Sum Rules

open access: yes, 2010
A novel procedure for extracting hadron characteristics from QCD sum rules, based on effective continuum thresholds (necessary for the implementation of quark-hadron duality) which may depend on the involved momenta and on the Borel parameter(s), enables

Anscombe on the shallowness of consequentialism

open access: yesEuropean Journal of Philosophy, Volume 33, Issue 2, Page 737-747, June 2025.
Abstract This paper is divided into two parts. In the first I outline and defend Elizabeth Anscombe's claim that consequentialism is a shallow philosophy by considering how two contemporary consequentialists reach opposing but equally outlandish moral conclusions on a matter as fundamental as whether it is good or bad that the human race continues.
