We investigate whether the subleading three nucleon contact interaction, depending on 10 low-energy constants (LECs), may provide enough flexibility to solve existing discrepancies between theory and experiment in A=3 scattering observables. To this aim we choose a realistic two-nucleon interaction (AV18) supplemented with the leading and subleading three-nucleon contact interaction, and fit the LECs to very precise data on polarization observables in elastic p−d scattering at 3 MeV proton energy.

Abstract

We investigate whether the subleading three nucleon contact interaction, depending on 10 low-energy constants (LECs), may provide enough flexibility to solve existing discrepancies between theory and experiment in A=3 scattering observables. To this aim we choose a realistic two-nucleon interaction (AV18) supplemented with the leading and subleading three-nucleon contact interaction, and fit the LECs to very precise data on polarization observables in elastic p−d scattering at 3 MeV proton energy.
