The spin structure of the nucleon [PDF]

open access: yesReports on progress in physics. Physical Society, 2018
We review the present understanding of the spin structure of protons and neutrons, the fundamental building blocks of nuclei collectively known as nucleons.

Few- and many-nucleon systems with semilocal coordinate-space regularized chiral two- and three-body forces [PDF]

open access: yesPhysical Review C, 2018
We present a complete calculation of nucleon-deuteron scattering as well as ground and low-lying excited states of light nuclei in the mass range A=3-16 up through next-to-next-to-leading order in chiral effective field theory using semilocal coordinate ...

Few-nucleon and many-nucleon systems with semilocal coordinate-space regularized chiral nucleon-nucleon forces [PDF]

open access: yesPhysical Review C, 2018
We employ a variety of ab initio methods including Faddeev-Yakubovsky equations, No-Core Configuration Interaction Approach, Coupled-Cluster Theory and In-Medium Similarity Renormalization Group to perform a comprehensive analysis of the nucleon-deuteron

Phenomenology of the nucleon-nucleon potential

open access: yesOpen Physics, 2010
AbstractA local nucleon-nucleon potential expansion is developed in terms of orthogonal projectors. Considering the nucleon-nucleon (NN) potential as a completely phenomenological structure, the expansion provides an opportunity to obtain the NN scattering phase shifts that can be described by applying a restricted set of operators, dependent on ...

Nucleon-nucleon correlations, short-lived excitations, and the quarks within [PDF]

open access: yes, 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]

open access: yesPhysical 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 ...

Chromo-Electric Field Energy in Quark Models

open access: yesFrontiers in Physics, 2019
We study the contribution of the chromo-electric field to the total energy of the hadrons. We analyze the case of quarks considered as extended sources of the field. Specific forms of the interaction potential of the quarks are obtained.

Nucleon-nucleon data [PDF]

open access: yes, 1997
This is the final report of a one-year, Laboratory Directed Research and Development (LDRD) project at Los Alamos National Laboratory (LANL). This work completes the determination of the nucleon-nucleon (NN) scattering amplitudes from 485 to 800 MeV. The data set is completed by the publication of two papers. These new data have a precision better than

New Laser Fusion and Its Gain by Intense Laser

open access: yesEnergies, 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 ...

Accurate nucleon-nucleon potential with charge-independence breaking.

open access: yesPhysical 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}.
