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

Pion-nucleon scattering in covariant baryon chiral perturbation theory with explicit Delta resonances [PDF]
, 2016 A bstractWe present the results of a third order calculation of the pion-nucleon scattering amplitude in a chiral effective field theory with pions, nucleons and delta resonances as explicit degrees of freedom.

The structure of the nucleon: Elastic electromagnetic form factors [PDF]
European Physical Journal A, 2015 Precise proton and neutron form factor measurements at Jefferson Lab, using spin observables, have recently made a significant contribution to the unraveling of the internal structure of the nucleon. Accurate experimental measurements of the nucleon form

NEUTRINO-DRIVEN EXPLOSION OF A 20 SOLAR-MASS STAR IN THREE DIMENSIONS ENABLED BY STRANGE-QUARK CONTRIBUTIONS TO NEUTRINO–NUCLEON SCATTERING [PDF]
, 2015 Interactions with neutrons and protons play a crucial role for the neutrino opacity of matter in the supernova core. Their current implementation in many simulation codes, however, is rather schematic and ignores not only modifications for the correlated

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

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.

A novel nuclear dependence of nucleon–nucleon short-range correlations
Physics Letters B, 2017 A linear correlation is found between the magnitude of nucleon–nucleon short-range correlations and the nuclear binding energy per nucleon with pairing energy removed.

Field transformations and simple models illustrating the impossibility of measuring off-shell effects [PDF]
, 1999 In the context of simple models illustrating field transformations in Lagrangian field theories we discuss the impossibility of measuring off-shell effects in nucleon-nucleon bremsstrahlung, Compton scattering, and related processes.

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 ...
