Testing Non-local Nucleon-Nucleon Interactions in the Four-Nucleon Systems [PDF]
Phys.Rev. C70 (2004) 044002, 2004 The Faddeev-Yakubovski equations are solved in configuration space for the $% \alpha$-particle and n-$^3$H continuum states. We test the ability of nonlocal nucleon-nucleon interaction models to describe 3N and 4N systems.

Role of the total isospin 3/2 component in three-nucleon reactions [PDF]
, 2016 We discuss the role of the three-nucleon isospin T=3/2 amplitude in elastic neutron-deuteron scattering and in the deuteron breakup reaction. The contribution of this amplitude originates from charge-independence breaking of the nucleon-nucleon potential

Three-nucleon force effects in inclusive spectra of the neutron-deuteron breakup reaction [PDF]
, 2020 We investigate the sensitivity of the non-exclusive nucleon induced deuteron breakup reaction to the three-nucleon interaction and distributions of three-nucleon force effects in inclusive spectra. To this end we solve the three-nucleon Faddeev equation at a number of incoming nucleon laboratory energies using the CD Bonn nucleon-nucleon interaction ...

Antinucleon-nucleon interaction in chiral effective field theory [PDF]
, 2013 Results of an exploratory study of the antinucleon-nucleon interaction within chiral effective field theory are reported. The antinucleon-nucleon potential is derived up to next-to-next-to-leading order, based on a modified Weinberg power counting, in ...

Nucleon–nucleon interactions on the lattice [PDF]
Physics Letters B, 2002 We consider the nucleon-nucleon potential in quenched and partially-quenched QCD. The leading one-meson exchange contribution to the potential is found to fall off exponentially at long-distances, in contrast with the Yukawa-type behaviour found in QCD. This unphysical component of the two-nucleon potential has important implications for the extraction

A new way to perform partial wave decompositions of few-nucleon forces [PDF]
, 2009 We formulate a general and exact method of partial wave decomposition (PWD) of any nucleon-nucleon (NN) potential and any three-nucleon (3N) force. The approach allows one to efficiently use symbolic algebra software to generate the interaction dependent

Inelasticity in Nucleon-Nucleon and Nucleon-Nucleus Collision [PDF]
Progress of Theoretical Physics, 1992 pseudo·rapidity 5). It was found that for both parametrizations the inelasticity in pp collision decreases when energy increases and for proton· air nucleus the inelasticity has also a moderate decrease with the energy. However for proton· nucleus the inelasticity has a strong sensitivity with the mass number of the nucleus. Using our calculations for

Low-energy neutron-deuteron reactions with N3LO chiral forces [PDF]
, 2014 We solve three-nucleon Faddeev equations with nucleon-nucleon and three-nucleon forces derived consistently in the framework of chiral perturbation theory at next-to-next-to-next-to-leading order in the chiral expansion.

Nonmesonic weak decay of Λ hypernuclei: The three-nucleon induced mode
Physics Letters B, 2017 The nonmesonic weak decay of Λ hypernuclei is studied within a microscopic diagrammatic approach which is extended to include the three-nucleon induced mechanism.
