Various types of theoretical uncertainties by example of the elastic nucleon-deuteron scattering spin correlation coefficient Cz,x [PDF]

EPJ Web of Conferences, 2019
The elastic nucleon-deuteron scattering process can be used to study three-nucleon dynamics, but in order to draw reliable conclusions based on the comparison of theoretical predictions and data, an estimation of theoretical uncertainties is necessary ...

Low-energy theorems for nucleon-nucleon scattering at M π = 450 MeV [PDF]

, 2016
We apply the low-energy theorems to analyze the recent lattice QCD results for the two-nucleon system at a pion mass of ${M}_{\ensuremath{\pi}}\ensuremath{\simeq}450$ MeV obtained by the NPLQCD Collaboration.

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.

Sensitivity of nucleon-nucleus scattering to the off-shell behavior of on-shell equivalent NN potentials [PDF]

, 1996
The sensitivity of nucleon-nucleus elastic scattering to the off-shell behavior of realistic nucleon-nucleon interactions is investigated when on-shell equivalent nucleon-nucleon potentials are used. The study is based on applications of the full-folding

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.

Quasi-free proton knockout from 12C on carbon target at 398 MeV/u

Physics Letters B, 2019
The proton-removal mechanism of the 12C→11B reaction induced on a carbon target via elementary nucleon-nucleon scattering is investigated in exclusive triple-coincidence measurements.

Repulsive Core of NN S-Wave Scattering in a Quark Model with a Condensed Vacuum [PDF]

, 1997
We work in a chiral invariant quark model, with a condensed vacuum, characterized by only one parameter. Bound state equations for the nucleon and Delta are solved in order to obtain an updated value of their radii and masses.

Pion–nucleon scattering: from chiral perturbation theory to Roy–Steiner equations

EPJ Web of Conferences, 2016
Ever since Weinberg’s seminal predictions of the pion–nucleon scattering amplitudes at threshold, this process has been of central interest for the study of chiral dynamics involving nucleons.
