Analyzing power in nucleon-deuteron scattering and three-nucleon forces
Three-nucleon forces have been considered to be one possibility to resolve the well known discrepancy between experimental values and theoretical calculations of the nucleon analyzing power in low energy nucleondeuteron scattering. In this paper, we investigate possible effects of twopion exchange three-nucleon forces on the analyzing power and the differential cross section. We found that the ...
متن کاملSpin observables in nucleon-deuteron scattering and three-nucleon forces
Three-nucleon forces, which compose an up-to-date subject in few-nucleon systems, provide a good account of the triton binding energy and the cross section minimum in proton-deuteron elastic scattering. However, three-nucleon forces do not explain spin observables such as the nucleon and deuteron analyzing powers, suggesting serious defects in their spin dependence. We study the spin structure ...
متن کاملHolographic Deuteron and Nucleon-Nucleon Potential
We compute the potential between a pair of nucleons in the D4-D8 holographic QCD. In the large ’t Hooft coupling limit, λ ≫ 1, the hadronic size of the baryon is small ∼ 1/ √ λMKK , and their interaction with mesons are well approximated by a set of dimension four and five operators. The nucleon-nucleon potential emerges from one-boson exchange picture involving massless pseudo-scalars and an i...
متن کاملNucleon Polarisabilities from Compton Scattering on the Deuteron
An analytic calculation of the differential cross section for elastic Compton scattering on the deuteron at photon energies ω in the range of 25 − 50 MeV is presented to next-to-next-to-leading order, i.e. to an accuracy of ∼ 3%. The calculation is model-independent and performed in the low energy nuclear Effective Field Theory without dynamical pions. The iso-scalar, scalar electric and magnet...
متن کاملDeuteron Compton Scattering and Electromagnetic Polarizabilities of the Nucleon *
Differential cross section of deuteron Compton scattering has been calculated using the Bonn NN-potential, a consistent set of meson-exchange currents and seagulls, and lowest-and higher-order electromagnetic polarizabilities of the nucleon. Estimates of the polarizabilities of the neutron are obtained from recent experimental data. Photon scattering is a powerful tool for probing the structure...
