Wolfenstein Amplitudes Derived from a Chiral NN Interaction up to N4LO
ORAL
Abstract
Chiral nucleon-nucleon (NN) interactions are successful at describing two and three nucleon forces, and in
the two-nucleon sector their constants are fitted to NN observables.
This talk focuses on the Epelbaum-Krebs-Meissner (EKM) NN interaction with a local coordinate-space regulator.
From a given NN interaction, one usually calculates phase shifts, which are then used to determine scattering
observables.
An intermediate step is to construct Wolfenstein amplitudes from the phase shifts, which may allow to
investigate their connection to the operator structure of the NN interaction.
In this talk, the Wolfenstein amplitudes and their dependence on the NN laboratory energy up to 200 MeV
as well as the cutoff parameter will be shown. Furthermore, the contributions of the different partial waves
to each amplitude will be investigated.
