Nucleon-nucleon correlations, short-lived excitations, and the quarks within [PDF]
, 2016 This article reviews our current understanding of how the internal quark structure of a nucleon bound in nuclei differs from that of a free nucleon. We focus on the interpretation of measurements of the EMC effect for valence quarks, a reduction in the ...

High-Precision Determination of the Pion-Nucleon σ Term from Roy-Steiner Equations. [PDF]
Physical Review Letters, 2015 We present a determination of the pion-nucleon (πN) σ term σ_{πN} based on the Cheng-Dashen low-energy theorem (LET), taking advantage of the recent high-precision data from pionic atoms to pin down the πN scattering lengths as well as of constraints ...

New Laser Fusion and Its Gain by Intense Laser
Energies, 2010 The feasibility of a new approach of laser fusion in plasma without implosion has been proposed and is discussed using an intense laser. The cross section of the nuclear reaction is increased by enhancing the penetrability of nuclei through the Coulomb ...

Four-nucleon system with $\Delta$-isobar excitation [PDF]
, 2008 The four-nucleon bound state and scattering below three-body breakup threshold are described based on the realistic coupled-channel potential CD Bonn + $\Delta$ which allows the excitation of a single nucleon to a $\Delta$ isobar.

Accurate nucleon-nucleon potential with charge-independence breaking.
Physical review. C, Nuclear physics, 1995 The authors present a new high-quality nucleon-nucleon potential with explicit charge dependence and charge asymmetry, which they designate Argonne {upsilon}{sub 18}.

Quark Models of the Nucleon–Nucleon Interaction
Frontiers in Physics, 2020 The present paper aims to provide a review of the relevance of quark degrees of freedom in the description of the nucleon-nucleon and, in general, of the baryon-baryon interaction.

The nucleon-nucleon interaction [PDF]
Brazilian Journal of Physics, 2004 Recent developements in our understanding of the fundamental nucleon-nucleon interaction are reviewed. Among the topics considered are (1) the so-called high-precision nucleon-nucleon potentials that emerged in the mid 1990s, (2) progress in the microscopic description of the intermediate-range part of the nucleon-nucleon interaction in terms of ...

The potential of the modified Thomas - Fermi method and its analytical representation on the example of the interaction of 16O with tin isotopes 112,114,116,118,120,122,124Sn [PDF]
Ядерна фізика та енергетика, 2023 Nucleon distribution densities and nucleus-nucleus interaction potentials for the 16O nucleus and 112,114,116,118,120,122,124Sn isotopes were calculated within the framework of the modified Thomas - Fermi method, taking into account all terms to the ...

Four-nucleon force in chiral effective field theory [PDF]
, 2005 We derive the leading contribution to the four-nucleon force within the framework of chiral effective field theory. It is governed by the exchange of pions and the lowest-order nucleon-nucleon contact interaction and includes effects due to the nonlinear

On Lattice Calculation of Electric Dipole Moments and Form Factors of the Nucleon [PDF]
, 2017 We analyze commonly used expressions for computing the nucleon electric dipole form factors (EDFF) $F_3$ and moments (EDM) on a lattice and find that they lead to spurious contributions from the Pauli form factor $F_2$ due to inadequate definition of ...
