Theoretical Nucleon-Nucleon Potential

Physical Review, 1963
The two-pion exchange nucleon-nucleon potential is calculated on the basis of the Mandelstam representation of the field-theoretic scattering amplitude. The results contain parameters referring to low-energy pion-nucleon scattering and the renormalized coupling constant $g$ only. A comparison of these results with phenomenological potentials is made.

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.

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 ...

Field-Theoretical Nucleon-Nucleon Potential

Physical Review D, 1969
A formulation is presented for the derivation of a Schr\"odinger-equation potential from a field-theoretical model. The relativistic two-body equation of Bethe and Salpeter is reduced using a generalization of the Blankenbecler-Sugar method. The resulting equation is shown to be identical with the nonrelativistic Lippmann-Schwinger equation upon a ...

Nucleon-nucleon bremsstrahlung: Anomalous magnetic moment effects

Physical Review C, 2006
Background: Two soft-photon amplitudes, the two-u-two-t special ( TuTts) amplitude and the Low amplitude, are known to produce quantitatively similar npy cross sections, but they predict quite different pp. cross sections for those kinematic conditions in which the nucleon scattering angles are small ( less than 25 degrees.).

Nucleon-nucleon Hamiltonian from Skyrmions

Physical Review D, 1991
We derive a Hamiltonian for two interacting nucleons starting directly from the Skyrme Lagrangian. Apart from the order-${N}_{c}$ (number of colors) "adiabatic" potential, we find a term of order $\sqrt{{N}_{c}}$ due to the fact that the static two-soliton configuration is not a solution to Hamilton's equations. Using a double expansion in ${{N}_{c}}^{\
