A per-cent-level determination of the nucleon axial coupling from quantum chromodynamics [PDF]
Nature, 2018 The axial coupling of the nucleon, gA, is the strength of its coupling to the weak axial current of the standard model of particle physics, in much the same way as the electric charge is the strength of the coupling to the electromagnetic current.

Revisiting the mechanical properties of the nucleon [PDF]
The European Physical Journal C, 2018 We discuss in detail the distributions of energy, radial pressure and tangential pressure inside the nucleon. In particular, this discussion is carried on in both the instant form and the front form of dynamics.

Towards high-order calculations of three-nucleon scattering in chiral effective field theory [PDF]
European Physical Journal A, 2019 We discuss the current status of chiral effective field theory in the three-nucleon sector and present selected results for nucleon–deuteron scattering observables based on semilocal momentum-space-regularized chiral two-nucleon potentials together with ...

Equation of state of nucleon matter and neutron star structure [PDF]
, 1998 Properties of dense nucleon matter and the structure of neutron stars are studied using variational chain summation methods and the new Argonne ${v}_{18}$ two-nucleon interaction, which provides an excellent fit to all of the nucleon-nucleon scattering ...

The spin structure of the nucleon [PDF]
Reports 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]
Physical 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 ...

Nucleon-Nucleon Scattering Up to N5LO in Chiral Effective Field Theory
Frontiers in Physics, 2020 During the past few decades a large effort has been made toward describing the NN interaction in the framework of chiral Effective Field Theory (EFT). The main idea is to exploit the symmetries of QCD to obtain an effective theory for low energy nuclear ...

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

Chromo-Electric Field Energy in Quark Models
Frontiers 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.

, 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
