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.

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-

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.

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 ...

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 ...

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.

Nucleon charges with dynamical overlap fermions [PDF]
Physical Review D, 2018 We calculate the scalar and tensor charges of the nucleon in $2+1$-flavor lattice QCD, for which the systematics of the renormalization of the disconnected diagram is well controlled.

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 ...

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
