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.

Nucleon and pion structure with lattice QCD simulations at physical value of the pion mass

open access: yes, 2015
We present results on the nucleon scalar, axial and tensor charges as well as on the momentum fraction, and the helicity and transversity moments. The pion momentum fraction is also presented. The computation of these key observables is carried out using

Flavor structure of the nucleon sea from lattice QCD [PDF]

open access: yes, 2014
We present the first direct lattice calculation of the isovector sea-quark distributions in the nucleon within the framework of the large-momentum effective field theory proposed recently.

Experimental progress and status on nucleon electromagnetic form factors

open access: yesEPJ Web of Conferences, 2016
Nucleon electromagnetic form factors are the fundamental quantities that are related to a two-dimensional view of the charge and magnetization distribution in the nucleon. They are essential in understanding the nucleon electromagnetic structure. In this

Simulation of a Three‐Nucleons System Transition on Quantum Circuits

open access: yesAdvanced Quantum Technologies, Volume 8, Issue 5, May 2025.
A general procedure is presented to calculate the transition probability for two nuclear states and a transition operator. The ground state is approximated through the variational quantum eigensolver and the first excited one using more sophisticated variational algorithms.

Study of fusion cross-sections of 16O + 208Pb and 28Si + 208Pb reactions by effective soft-core nucleon-nucleon interaction [PDF]

open access: yesNuclear Technology and Radiation Protection, 2007
In this paper, the cross-sections of fusion reactions 16O + 208Pb, 28Si + 208Pb, 40C + + 40Ca, 40Ca + 48Ca, 58Ni + 58Ni, and 16O + 154Sm at bombarding energies above and near the fusion barrier have been investigated.

A Compact Solution for Improving the Spatial Density of Observations of Large Ground Level Enhancements

open access: yesSpace Weather, Volume 23, Issue 5, May 2025.
Abstract Ground level enhancements (GLEs), which occur when high energy solar protons reach Earth, are a considerable space weather hazard for aviation activities. Neutron monitor (NM) observations of these events are the key input to operational models of ionizing radiation at aviation altitudes.

Neutron properties from light nuclei

open access: yesEPJ Web of Conferences, 2017
We review the achievements of the project B.6. Topics addressed include pion photoproduction of three-nucleon systems, electromagnetic and axial currents in chiral nuclear EFT, aspects of EFTs with spin-3/2 fields, nuclear structure and dynamics from the

Electron Phase Space Densities in Geostationary Orbits as Measured With GK2A, GOES‐16, and GOES‐17 Satellites

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.
Abstract This study investigated electron phase space densities (PSDs) in geostationary orbits using data from Korea's geostationary satellite, GK2A, as well as GOES‐16 and GOES‐17 satellites. The PSDs were computed from electron fluxes measured by each satellite during a geomagnetically quiet period as defined by stringent conditions on geomagnetic ...
