Nucleon Structure and Strong Interactions in Dark Matter Capture in Neutron Stars.

Physical Review Letters, 2020
We outline two important effects that are missing from most evaluations of the dark matter capture rate in neutron stars. As dark matter scattering with nucleons in the star involves large momentum transfer, nucleon structure must be taken into account ...

The Nucleon‐Nucleon Interaction

Fortschritte der Physik, 1978
A review is given of some of the theoretical ideas about the NN-interaction. Topics covered are: a discussion of the Bonn (1986), Paris (1980), and the Nijmegen (1978) potentials, a new phase shift analysis of the pp-data giving the preliminary value for the ppπ0 coupling constant g 0 2 /4π = 13.15 ± 0.2, and a discussion of the charge symmetry and ...

NUCLEON-NUCLEON AND HYPERON-NUCLEON INTERACTIONS

International Journal of Modern Physics E, 2001
The nucleon-nucleon and hyperon-nucleon interactions are studied by the one-boson-exchange(OBE) potential with the vertex form factor. To make our theory as relativistic as possible, we calculate the OBE-potential in the momentum space and use the Blankenbecler-Sugar equation.

Semilocal momentum-space regularized chiral two-nucleon potentials up to fifth order

, 2017
.We introduce new semilocal two-nucleon potentials up to fifth order in the chiral expansion. We employ a simple regularization approach for the pion exchange contributions which i) maintains the long-range part of the interaction, ii) is implemented in ...

The Padua model of the nucleon and the nucleon-nucleon potential

Il Nuovo Cimento A, 1991
The essential aspects of a new model of the nucleon are developed, and a nucleon-nucleon potential is therefrom deduced in the framework of the meson exchange theory. The preliminary results are promising and the model discloses interesting theoretical perspectives.

Study of Nucleon-Nucleon and Hyperon-Nucleon Interaction

Progress of Theoretical Physics Supplement, 2000
In this paper we review recent investigations of nucleon-nucleon andhyperon-nucleon interactions employing a non-relativistic quark cluster model. We concentrate mainly on the short andmed ium-range behavior of the baryon-baryon interaction basedon the onegluon andmeson exchange potentials. The chiral quark mod el basedon pion andsigma exchange between

Nucleon-Nucleon Scattering

Physical Review, 1956
Nucleon-nucleon scattering data from 0 to 274 Mev are discussed by means of a boundary-condition approximation. For internucleon distances greater than the core radius, which may depend on the state under discussion, the nucleon-nucleon interaction is assumed to vanish, while at the core radius the logarithmic derivative of the wave function or the ...

Accurate charge-dependent nucleon-nucleon potential at fourth order of chiral perturbation theory [PDF]

Physical Review C, 2003
We present the first nucleon-nucleon potential at next-to-next-to-next-to-leading order (fourth order) of chiral perturbation theory. Charge dependence is included up to next-to-leading order of the isospin-violation scheme.

The nucleon nucleon interaction

Nuclear Physics A, 1980
Abstract In this session we have 25 contributed papers. Those concerned with the new results of the Basque group (n-p elastic differential and total cross sections in the energy range 210–500 MeV) and of the Geneva group (measurement of correlation parameters in p−p elastic scattering between 400–600 MeV) were reported on by D. Bugg1).
