The sensitivity of proton-nucleus elastic scattering to different nucleon-nucleon effective interactions is studied within the framework of the nonrelativistic full-folding model. Calculations of the nucleon-nucleus optical potential are made using the free nucleon-nucleon t-matrices generated from the Bonn, Paris, Hamada-Johnston, and Melbourne nucleon-nucleon potentials, whose full off-shell ...

The sensitivity of nucleon-nucleus elastic scattering to the off-shell behavior of realistic nucleon-nucleon interactions is investigated when on-shell equivalent nucleon-nucleon potentials are used. The study is based on applications of the full-folding optical model potential for an explicit treatment of the off-shell behavior of the nucleon-nucleon effective interaction. Applications were ma...

We investigate the importance of three-nucleon ($3N$) force contact terms in elastic nucleon-deuteron ($Nd$) scattering by applying $\mathrm{N}^{4}\mathrm{LO}^{+}$ chiral semilocal momentum space (SMS) regularized nucleon-nucleon potential supplemented $\mathrm{N}^{2}\mathrm{LO}$ and all subleading $\mathrm{N}^{4}\mathrm{LO}$ terms. Strength parameters were obtained least squares fitting theore...

Hadronic elastic and transition form factors are used to describe elastic nucleon-nucleon and pion-nucleon scattering, as well as diffractive excitation of nucleon resonances in an optical model. Very good quantitative agreement with available experimental results is obtained.

Using Dyson–Schwinger equations, the nucleon propagator is analyzed nonperturbatively in a field–theoretical model for the pion–nucleon interaction. Infinities are circumvented by using pion–nucleon form factors which define the physical scale. It is shown that the correct, finite, on–shell nucleon renormalization is important for the value of the mass–shift and the propagator. For physically a...

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 ...
