Deconstructing triplet nucleon-nucleon scattering

open access: yes, 2007
Nucleon-nucleon scattering in spin-triplet channels is analysed within an effective field theory where one-pion exchange is treated nonperturbatively. Justifying this requires the identification of an additional low-energy scale in the strength of that ...

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

177LU-PSMA AND 177LU-DOTATATE AS THERAPY ALTERNATIVES FOR METACHRONOUS TRANSDIFFERENTIATED PROSTATE AND NEUROENDOCRINE TUMORS - CASE REPORT

open access: yesHematology, Transfusion and Cell Therapy
Introduction/Justification: Prostate cancer is among the most common cancers in males. The PSMA (Prostate-Specific Membrane Antigen), a protein expressed in prostate cancer cells, has been used in the control of that cancer and can also be taken up in ...

Contributions of chiral two- and three-nucleon interactions to closed shell nuclei

open access: yesEPJ Web of Conferences, 2016
Using two-nucleon force alone is usually inadequate to interpret nuclear systems’ experimental data. We adopt a chiral N3LO two-nucleon potential V2N with the inclusion of an in-medium three-nucleon (NNN) force V̄3N to calculate binding energies of ...

Local Nucleon-Nucleon and Three-Nucleon Interactions Within Chiral Effective Field Theory

open access: yesFrontiers in Physics, 2020
To obtain an understanding of the structure and reactions of nuclear systems from first principles has been a long-standing goal of nuclear physics. In this respect, few- and many-body systems provide a unique laboratory for studying nuclear interactions.

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

open access: yesMedical Physics, Volume 52, Issue 6, Page 4924-4940, June 2025.
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 ...

Pion–nucleon scattering: from chiral perturbation theory to Roy–Steiner equations

open access: yesEPJ Web of Conferences, 2016
Ever since Weinberg’s seminal predictions of the pion–nucleon scattering amplitudes at threshold, this process has been of central interest for the study of chiral dynamics involving nucleons.

Strangeness on the nucleon [PDF]

open access: yesAIP Conference Proceedings, 2013
Observables from parity violation in elastic electron-nucleon scattering and neutral current quasi-elastic neutrino-nucleus scattering are employed as tools to improve the current knowledge on the strangeness content in the nucleon.

Chiral Corrections to Nucleon Two- and Three-Point Correlation Functions

open access: yes, 2015
We consider multi-particle contributions to nucleon two- and three-point functions from the perspective of chiral dynamics. Lattice nucleon interpolating operators, which have definite chiral transformation properties, can be mapped into chiral ...

Genetic and morphological variation in the genus Zygogonium (Zygnematophyceae, Charophyta) from localities in Europe and North America and description of Z. angustum, sp. nov.

open access: yesJournal of Phycology, Volume 61, Issue 3, Page 587-606, June 2025.
Abstract The globally distributed genus Zygogonium exhibits a narrow environmental range, with 19 morphologically described species. Its molecular characterization is poor, based on a single accession of the type species Z. ericetorum from Austria.
