High-momentum components in the 4He nucleus caused by inter-nucleon correlations

open access: yesPhysics Letters B, 2020
High-momentum components of nuclei are essential for understanding the underlying inter-nucleon correlations in nuclei. We perform the comprehensive analysis for the origin of the high-momentum components of 4He in the framework of Tensor-optimized High ...

The Nambu-Jona-Lasinio model of light nuclei [PDF]

open access: yes, 2000
The Nambu-Jona-Lasinio model of the deuteron suggested by Nambu and Jona-Lasinio (Phys. Rev. 124 (1961) 246) is formulated from the first principles of QCD. The deuteron appears as a neutron-proton collective excitation, i.e. a Cooper np-pair, induced by

On the impact of mass difference between the pions (π±-π0) and the nucleons (n-p) on the charge independence breaking of nuclear forces

open access: yesЯдерна фізика та енергетика, 2017
Charge dependence of the pion-nucleon coupling constants and the 1S0-state low-energy nucleon-nucleon scattering parameters are studied on the basis of the Yukawa meson theory.

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.

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

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.
