Relativity and the low energy nd Ay puzzle [PDF]
, 2008 We solve the Faddeev equation in an exactly Poincare invariant formulation of the three-nucleon problem. The dynamical input is a relativistic nucleon-nucleon interaction that is exactly on-shell equivalent to the high precision CDBonn NN interaction.

Nucleon-nucleon bremsstrahlung of dark gauge bosons and revised supernova constraints [PDF]
, 2015 We calculate the rate of production of hypothetical light vector bosons (LVBs) from nucleon-nucleon bremsstrahlung reactions in hot and dense matter. We use the soft-radiation approximation and express the rates directly in terms of the measured nucleon ...

Matching Pion-Nucleon Roy-Steiner Equations to Chiral Perturbation Theory. [PDF]
Physical Review Letters, 2015 We match the results for the subthreshold parameters of pion-nucleon scattering obtained from a solution of Roy-Steiner equations to chiral perturbation theory up to next-to-next-to-next-to-leading order, to extract the pertinent low-energy constants ...

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.

Nuclear structure studies within the realistic shell model [PDF]
EPJ Web of ConferencesThe 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

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 ...

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 ...

Low-energy neutron-deuteron reactions with N3LO chiral forces [PDF]
, 2014 We solve three-nucleon Faddeev equations with nucleon-nucleon and three-nucleon forces derived consistently in the framework of chiral perturbation theory at next-to-next-to-next-to-leading order in the chiral expansion.

Proton electromagnetic generalized polarizabilities
Frontiers in PhysicsElectromagnetic 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 ...

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
