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 ...

Chiral effective field theories for strong and weak dynamics

open access: yesJournal of High Energy Physics
The chiral effective field theory (ChEFT) is an extension of the chiral perturbation theory that includes the nuclear forces and weak currents at the hadronic and nuclear scales.

Regularization methods for Nuclear Lattice Effective Field Theory

open access: yesPhysics Letters B, 2015
We investigate Nuclear Lattice Effective Field Theory for the two-body system for several lattice spacings at lowest order in the pionless as well as in the pionful theory.

Probing the isospin dependent mean field and nucleon nucleon cross section in the medium by the nucleon emissions

open access: yes, 2003
We study the isospin effects of the mean field and two-body collision on the nucleon emissions at the intermediate energy heavy ion collisions by using an isospin dependent transport theory.

Complete Set of Deuteron Analyzing Powers for dp Elastic Scattering at 250 MeV/nucleon and Three Nucleon Forces

open access: yesEPJ Web of Conferences, 2010
Measurements of a complete set of deuteron analyzing powers (iT11, T20, T21, T22) for elastic deuteron–proton scattering at 250 MeV/nucleon have been performed with polarized deuteron beams at RIKEN RI Beam Factory.

Probing the density dependence of the symmetry energy by nucleon flow

open access: yes, 2018
In the framework of the isospin-dependent Boltzmann-Uehling-Uhlenbeck transport model, sensitive regions of some nucleon observables to the nuclear symmetry energy are studied. It is found that the symmetry energy sensitive observable n/p ratio in the $^{

Three-nucleon force effects in proton-deuteron scattering

open access: yesEPJ Web of Conferences, 2010
Possible three-nucleon forces that may be considered in addition to a widely accepted two-pion exchange three-nucleon force are studied to improve the fit to experimental data of proton-deuteron scattering.

Diquark Corrleations in the nucleon structure function

open access: yes, 1993
The nucleon structure functions are studied with a special emphasis on diquark correlations inside the nucleon. Assuming a phenomenological diquark-quark model of the nucleon at the low energy hadronic scale, we calculate the leading twist contributions ...

Recent results on deuteron–proton scattering from RIKEN

open access: yesEPJ Web of Conferences, 2016
Nucleon-deuteron (Nd) scattering, for which a rigorous formulation in terms of Faddeev equations exists and exact solutions of these equations for any dynamical input can be obtained, offers a good opportunity to study the dynamical aspects of 3NFs, such

Nucleon-deuteron capture with chiral potentials [PDF]

open access: yes, 2006
Present day chiral nucleon-nucleon potentials up to N3LO and three nucleon forces at N2LO are used to analyze nucleon-deuteron radiative capture at deuteron lab energies below E_d= 100 MeV. The differential cross section and the deuteron analyzing powers
