Pion-mass dependence of the nucleon-nucleon interaction
Nucleon-nucleon interactions, both bare and effective, play an important role in our understanding of the non-perturbative strong interaction, as well as nuclear structure and reactions.

Few-nucleon system dynamics in medium energy domain
Nucleon-nucleon interactions and hyperon nucleon interactions are study in three body final state with one being a meson. In addition to final state parameters possible resonances in the two baryon states are of interest.

Antinucleon-nucleon interaction in chiral effective field theory
A study of the antinucleon-nucleon interaction within chiral effective theory is presented. This novel approach suggested by Weinberg for investigating nucleon-nucleon interaction can be adapted straightforwardly to the antinucleon-system.

Nucleon-nucleon interactions and observables [PDF]
A class of nucleon-nucleon interactions which are exactly phase equivalent to a given realistic nucleon-nucleon interaction are exhibited. These interaction have the property that the RMS radius of the deuteron can be made arbitrarily large without changing any of the scattering or bound-state observables.

We review on a novel chiral power counting scheme for in-medium chiral perturbation theory with nucleons and pions as degrees of freedom. It allows for a systematic expansion taking into account local as well as pion-mediated inter-nucleon ...

Chiral 2N and 3N interactions and quantum Monte Carlo applications
Chiral Effective Field Theory (EFT) two- and three-nucleon forces are now widely employed. Since they were originally formulated in momentum space, these interactions were non-local, making them inaccessible to Quantum Monte Carlo (QMC) methods.

Eta Prime Gluonic Contribution to the Nucleon Self-Energy in an Effective Theory
We estimate a possible η′ gluonic contribution to the self-energy of a nucleon in an effective theory. The couplings of the topological charge density to nucleons give rise to OZI violating η′-nucleon interactions.

Ab initio study of neutron drops with chiral Hamiltonians
We report ab initio calculations for neutron drops in a 10 MeV external harmonic-oscillator trap using chiral nucleon–nucleon plus three-nucleon interactions. We present total binding energies, internal energies, radii and odd–even energy differences for

High-momentum components in the 4He nucleus caused by inter-nucleon correlations
High-momentum components of nuclei are essential for understanding the underlying inter-nucleon correlations in nuclei. We perform the comprehensive analysis for the origin of the high-momentum components of 4He in the framework of Tensor-optimized High ...
