Poles in the SAID NN analysis

open access: yesEPJ Web of Conferences, 2014
The SAID approach to partial-wave analysis of nucleon-nucleon scattering data is reviewed. This has been applied to recent COSY np scattering data. The appearance of poles (dibaryons) is discussed in light of these new fits.

Three-nucleon force effects in nucleon-deuteron scattering at backward angles

open access: yesSciPost Physics Proceedings, 2020
Elastic and breakup cross sections in nucleon-deuteron scattering at intermediate energies are calculated using a realistic two-nucleon potential and three-nucleon potentials based on the exchange of two pions among three nucleons.

Chiral NN model and Ay puzzle [PDF]

open access: yes, 2001
We analyze the results by chiral NN models for the two-nucleon system and calculate the predictions for the nucleon vector analyzing power of elastic nucleon-deuteron (Nd) scattering, Ay, by these models.

LET measurements in proton and helium‐ion beams of therapeutic energies using a silicon pixel detector towards a tool for quality assurance

open access: yesMedical Physics, Volume 52, Issue 9, September 2025.
Abstract Background As advanced treatment plans increasingly include optimizing both dose and linear energy transfer (LET), there is a growing demand for tools to measure LET in clinical settings. Although various detection systems have been investigated in this pursuit, the scarcity of detectors capable of providing per‐ion data for a fast and ...

Constraining dark matter-nucleon scattering cross section by the background electron anti-neutrino flux data

open access: yesPhysics Letters B, 2022
Celestial objects such as stars and planets might be able to capture a large amount of dark matter particles through dark matter-nucleon scattering.

Weinbergʼs approach to nucleon–nucleon scattering revisited

open access: yesPhysics Letters B, 2012
We propose a new, renormalizable approach to nucleon-nucleon scattering in chiral effective field theory based on the manifestly Lorentz invariant form of the effective Lagrangian without employing the heavy-baryon expansion. For the pion-less case and for the formulation based on perturbative pions, the new approach reproduces the known results ...

The Curious Concept That Almost Nobody Seemed to Care About at First: Virtual Particles in the Post‐War Period**

open access: yesBerichte zur Wissenschaftsgeschichte, Volume 48, Issue 1-2, Page 143-162, August 2025.
Abstract Short‐lived, unobservable, and not subject to the usual rules of conservation of energy and momentum, virtual particles—an integral part of the conceptual framework of quantum field theory (QFT)—exhibit a number of curious characteristics which, in recent decades, have in part fueled important discussions about their ontological status ...

Nucleon-nucleon scattering at small angles, measured at ANKE-COSY

open access: yesEPJ Web of Conferences, 2016
The most accepted approach to describe nucleon-nucleon (NN) interaction is the partial wave analysis (PWA), which translates various experimental observables to the common language of the partial waves.

Ab initio Folding Potentials for Nucleon-Nucleus Scattering based on NCSM One-Body Densities [PDF]

open access: yes, 2018
Calculating microscopic optical potentials for elastic nucleon-nucleus scattering has already led to large body of work in the past. For folding first-order calculations the nucleon-nucleon (NN) interaction and the one-body density of the nucleus were ...

Two Micron‐Size Dark Dimensions

open access: yesFortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.
