Deconstructing triplet nucleon-nucleon scattering [PDF]

Physical Review C, 2007
Nucleon-nucleon scattering in spin-triplet channels is analysed within an effective field theory where one-pion exchange is treated nonperturbatively. Justifying this requires the identification of an additional low-energy scale in the strength of that ...

Deconstructing 1S0 nucleon-nucleon scattering [PDF]

The European Physical Journal A, 2010
A distorted-wave method is used to analyse nucleon-nucleon scattering in the 1S0 channel. Effects of one-pion exchange are removed from the empirical phase shift to all orders by using a modified effective-range expansion.

Recent Developments in Few-Nucleon Scattering [PDF]

EPJ Web of Conferences, 2010
Using modern nucleon-nucleon interactions in the description of the A = 3, 4 nuclei, it is not possible to reproduce both the three- and four-nucleon binding energies simultaneously.

Nucleon-Nucleon Scattering and Large N(c) QCD [PDF]

Proceedings of Xth Quark Confinement and the Hadron Spectrum — PoS(Confinement X), 2013
Nucleon-nucleon scattering observables are discussed in the context of large Nc QCD. As is well known, the baryon spectrum in the large Nc limit exhibits contracted SU(2Nf) spin-flavor sym- metry.

Non-localities in nucleon-nucleus potentials [PDF]

, 2007
Two causes of non-locality inherent in nucleon-nucleus scattering are considered. They are the results of two-nucleon antisymmetry of the projectile with each nucleon in the nucleus and the dynamic polarization potential representation of channel ...

Pionic hydrogen and deuterium [PDF]

EPJ Web of Conferences, 2022
The strong-interaction effects both in pionic hydrogen and deuterium atoms have been re-determined with improved precision. The hadronic shift and width in pionic hydrogen together with the hadronic shift in pionic deuterium constitute a one-fold ...

Chiral uncertainties in ab initio elastic nucleon-nucleus scattering

Frontiers in Physics, 2023
The effective interaction between a nucleon and a nucleus is one of the most important ingredients for reaction theories. Theoretical formulations were introduced early by Feshbach and Watson, and efforts of deriving and computing those ‘optical ...

Isotriplet pairing energy of nucleons in nuclei

Results in Physics, 2023
The problem of describing the nucleon pairing energy in nuclei is considered using a realistic nucleon-nucleon potential that reproduces the parameters of nucleon-nucleon scattering.

Nucleon-Nucleon Scattering Up to N5LO in Chiral Effective Field Theory

Frontiers in Physics, 2020
During the past few decades a large effort has been made toward describing the NN interaction in the framework of chiral Effective Field Theory (EFT). The main idea is to exploit the symmetries of QCD to obtain an effective theory for low energy nuclear ...
