Peripheral nucleon-nucleon scattering at fifth order of chiral perturbation theory [PDF]
, 2014 We present the two- and three-pion exchange contributions to the nucleon-nucleon interaction which occur at next-to-next-to-next-to-next-to-leading order (N4LO, fifth order) of chiral effective field theory, and calculate nucleon-nucleon scattering in ...

1S0 nucleon-nucleon scattering in the modified Weinberg approach [PDF]
, 2015 Nucleon-nucleon scattering in the 1S0 partial wave is considered in chiral effective field theory within the renormalizable formulation of a previous work (Phys. Lett. B 716, 338 (2012)) beyond the leading-order approximation.

More on Heisenberg’s model for high energy nucleon-nucleon scattering [PDF]
, 2015 We revisit Heisenberg's model for nucleon-nucleon scattering which admits a saturation of the Froissart bound. We examine its uniqueness, and find that up to certain natural generalizations, it is the only action that saturates the bound. We find that we

Nucleon-Nucleon Scattering Parameters in the Limit of SU(3) Flavor Symmetry [PDF]
, 2013 The scattering lengths and effective ranges that describe low-energy nucleon-nucleon scattering are calculated in the limit of SU(3)-flavor symmetry at the physical strange-quark mass with Lattice Quantum Chromodynamics.

Low-energy theorems for nucleon-nucleon scattering at unphysical pion masses [PDF]
, 2015 The longest-range part of the nuclear force due to the one-pion exchange governs the energy dependence of the scattering amplitude in the near-threshold region and imposes correlations between the coecients in the eective range expansion.

Nucleon-nucleon scattering with the complex scaling method and realistic interactions [PDF]
, 2014 We demonstrate the validity of the complex scaling method for realistic strong, non-local, nucleon- nucleon interactions by comparing the deuteron bound state and nucleon-nucleon scattering phase shifts with results from other high-precision methods ...

Nucleon-nucleon scattering from fully dynamical lattice QCD. [PDF]
Physical Review Letters, 2006 We present results of the first fully dynamical lattice QCD determination of nucleon-nucleon scattering lengths in the 1S0 channel and 3S1 - 3D1 coupled channels.

Perturbative Renormalizability of Chiral Two Pion Exchange in Nucleon-Nucleon Scattering: P- and D-waves [PDF]
, 2011 We study the perturbative renormalizability of chiral two pion exchange in nucleon-nucleon scattering for p- and d-waves within the effective field theory approach.

Low-energy theorems for nucleon-nucleon scattering [PDF]
, 1998 Low energy theorems are derived for the coefficients of the effective range expansion in s-wave nucleon-nucleon scattering valid to leading order in an expansion in which both $m_\pi$ and $1/a$ (where $a$ is the scattering length) are treated as small ...

Microscopic approach to the nucleon-nucleon effective interaction and nucleon-nucleon scattering in symmetric and isospin-asymmetric nuclear matter [PDF]
, 2013 After reviewing our microscopic approach to nuclear and neutron-rich matter, we focus on how nucleon-nucleon scattering is impacted by the presence of a dense hadronic medium, with special emphasis on the case where neutron and proton densities are ...
