Relativistic Effect on Low-Energy Nucleon-Deuteron Scattering

, 1994
The relativistic effect on differential cross sections, nucleon-to-nucleon and nucleon-to-deuteron polarization transfer coefficients, and the spin correlation function, of nucleon-deuteron elastic scattering is investigated employing several three ...

The chiral quark condensate and pion decay constant in nuclear matter at next-to-leading order [PDF]

, 2010
Making use of the recently developed chiral power counting for the physics of nuclear matter [1,2], we evaluate the in-medium chiral quark condensate up to next-to-leading order for both symmetric nuclear matter and neutron matter.

Nuclear structure studies within the realistic shell model [PDF]

EPJ Web of Conferences
The role of three-nucleon forces on structure properties of nuclei is discussed within the realistic shell model. Calculations are performed by employing effective shell-model Hamiltonians derived by way of many-perturbation theory from chiral potentials

Nonlocality of nucleon interaction and an anomalous off shell behavior of the two-nucleon amplitudes

, 2002
The problem of the ultraviolet divergences that arise in describing the nucleon dynamics at low energies is considered. By using the example of an exactly solvable model it is shown that after renormalization the interaction generating nucleon dynamics ...

Nuclear enthalpies

EPJ Web of Conferences, 2015
Even small departures from a nuclear equilibrium density with constant nucleon masses require an increase of a nucleon enthalpy. This process can be described as volume corrections to a nucleon rest energy, which are proportional to pressure and absent ...

Antinucleon-nucleon interaction in chiral effective field theory

EPJ Web of Conferences, 2018
A study of the antinucleon-nucleon interaction within chiral effective theory is presented. This novel approach suggested by Weinberg for investigating nucleon-nucleon interaction can be adapted straightforwardly to the antinucleon-system.

Proton electromagnetic generalized polarizabilities

Frontiers in Physics
Electromagnetic polarizabilities are fundamental properties of the proton that characterize its response to an external electromagnetic (EM) field. The generalization of the EM polarizabilities to non-zero four-momentum transfer opens up a powerful path ...

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 ...

A new way to perform partial wave decompositions of few-nucleon forces [PDF]

, 2009
We formulate a general and exact method of partial wave decomposition (PWD) of any nucleon-nucleon (NN) potential and any three-nucleon (3N) force. The approach allows one to efficiently use symbolic algebra software to generate the interaction dependent

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.
