Bayesian truncation errors in chiral effective field theory: Nucleon-nucleon observables [PDF]
, 2017 Chiral effective field theory (EFT) predictions are necessarily truncated at some order in the EFT expansion, which induces an error that must be quantified for robust statistical comparisons to experiment.

Improved chiral nucleon-nucleon potential up to next-to-next-to-next-to-leading order [PDF]
European Physical Journal A, 2014 We present improved nucleon-nucleon potentials derived in chiral effective field theory up to next-to-next-to-next-to-leading order. We argue that the nonlocal momentum-space regulator employed in the two-nucleon potentials of previous works (Nucl. Phys.

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 ...

Leading order relativistic chiral nucleon-nucleon interaction [PDF]
, 2016 Motivated by the successes of relativistic theories in studies of atomic/molecular and nuclear systems and the need for a relativistic chiral force in relativistic nuclear structure studies, we explore a new relativistic scheme to construct the nucleon ...

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

The potential of the modified Thomas - Fermi method and its analytical representation on the example of the interaction of 16O with tin isotopes 112,114,116,118,120,122,124Sn [PDF]
Âderna Fìzika ta Energetika, 2023 Nucleon distribution densities and nucleus-nucleus interaction potentials for the 16O nucleus and 112,114,116,118,120,122,124Sn isotopes were calculated within the framework of the modified Thomas - Fermi method, taking into account all terms to the ...

Elliptic flow in heavy ion collisions near the balance energy [PDF]
, 1999 The proton elliptic flow in collisions of Ca on Ca at energies from 30 to 100 MeV/nucleon is studied in an isospin-dependent transport model. With increasing incident energy, the elliptic flow shows a transition from positive to negative flow.

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

Leading order relativistic hyperon-nucleon interactions in chiral effective field theory [PDF]
, 2016 We apply a recently proposed covariant power counting in nucleon-nucleon interactions to study strangeness $S=-1$ $\Lambda N-\Sigma N$ interactions in chiral effective field theory. At leading order, Lorentz invariance introduces 12 low energy constants,
