Nuclear Spin-Isospin Correlations, Parity Violation, and the $f_\pi$ Problem [PDF]
, 2003 The strong interaction effects of isospin- and spin-dependent nucleon-nucleon correlations observed in many-body calculations are interpreted in terms of a one-pion exchange mechanism.

Role of the total isospin 3/2 component in three-nucleon reactions [PDF]
, 2016 We discuss the role of the three-nucleon isospin T=3/2 amplitude in elastic neutron-deuteron scattering and in the deuteron breakup reaction. The contribution of this amplitude originates from charge-independence breaking of the nucleon-nucleon potential

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 ...

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 ...

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 ...

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 ...

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

Four-nucleon system with $\Delta$-isobar excitation [PDF]
, 2008 The four-nucleon bound state and scattering below three-body breakup threshold are described based on the realistic coupled-channel potential CD Bonn + $\Delta$ which allows the excitation of a single nucleon to a $\Delta$ isobar.

Nonmesonic weak decay of Λ hypernuclei: The three-nucleon induced mode
Physics Letters B, 2017 The nonmesonic weak decay of Λ hypernuclei is studied within a microscopic diagrammatic approach which is extended to include the three-nucleon induced mechanism.
