The nucleon-nucleon interaction [PDF]

Journal of Physics G: Nuclear and Particle Physics, 2001
We review the major progress of the past decade concerning our understanding of the nucleon-nucleon interaction. The focus is on the low-energy region (below pion production threshold), but a brief outlook towards higher energies is also given. The items

An optimized chiral nucleon-nucleon interaction at next-to-next-to-leading order [PDF]

Physical Review Letters, 2013
We optimize the nucleon-nucleon interaction from chiral effective field theory at next-to-next- to-leading order. The resulting new chiral force NNLOopt yields \chi^2 \approx 1 per degree of freedom for laboratory energies below approximately 125 MeV. In

Precision nucleon-nucleon potential at fifth order in the chiral expansion [PDF]

Physical Review Letters, 2014
We present a nucleon-nucleon potential at fifth order in chiral effective field theory. We find a substantial improvement in the description of nucleon-nucleon phase shifts as compared to the fourth-order results of Ref. [E. Epelbaum, H. Krebs, U.-G. Mei{

The Off-Shell Nucleon-Nucleon Amplitude: Why it is Unmeasurable in Nucleon-Nucleon Bremsstrahlung [PDF]

, 2000
Nucleon-nucleon bremsstrahlung has long been considered a way of getting information about the off-shell nucleon-nucleon amplitude which would allow one to distinguish among nucleon-nucleon potentials based on their off-shell properties.

Improved axion emissivity from a supernova via nucleon-nucleon bremsstrahlung [PDF]

Journal of Cosmology and Astroparticle Physics, 2019
The most efficient axion production mechanism in a supernova (SN) core is the nucleon-nucleon bremsstrahlung. This process has been often modeled at the level of the vacuum one-pion exchange (OPE) approximation. Starting from this naive recipe, we revise

Constraining the Spin-Dependent WIMP-Nucleon Cross Sections with XENON1T. [PDF]

Physical Review Letters, 2019
We report the first experimental results on spin-dependent elastic weakly interacting massive particle (WIMP) nucleon scattering from the XENON1T dark matter search experiment. The analysis uses the full ton year exposure of XENON1T to constrain the spin-

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 ...
