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

Local Nucleon-Nucleon and Three-Nucleon Interactions Within Chiral Effective Field Theory [PDF]

Frontiers in Physics, 2020
To obtain an understanding of the structure and reactions of nuclear systems from first principles has been a long-standing goal of nuclear physics. In this respect, few- and many-body systems provide a unique laboratory for studying nuclear interactions.

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{

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

Pionic hydrogen and deuterium [PDF]

EPJ Web of Conferences, 2022
The strong-interaction effects both in pionic hydrogen and deuterium atoms have been re-determined with improved precision. The hadronic shift and width in pionic hydrogen together with the hadronic shift in pionic deuterium constitute a one-fold ...

Experimental Determination of the QCD Effective Charge α_g1(Q)

Particles, 2022
The QCD effective charge αg1(Q) is an observable that characterizes the magnitude of the strong interaction. At high momentum Q, it coincides with the QCD running coupling αs(Q).

Core-valence absorption in breakup and stripping reactions and its isospin dependence [PDF]

EPJ Web of Conferences, 2023
In this work, the effect of nucleon-core absorption on nucleon removal reaction is explored through the use of complex nucleon-core interactions. Results are presented for exclusive breakup reactions, where absorption is explored through the use of a ...

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

Measurement of the Tensor-Analyzing Power Component T₂₀ for Incoherent Negative Pion Photoproduction on a Deuteron

Atoms, 2023
New results for the T20-component of the tensor-analyzing power of the incoherent negative pion photoproduction are presented. The experiment was performed for the electron beam energy of 800 MeV at the VEPP-3 storage ring in 2021.

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-
