Abstract:
Three-nucleon forces are crucial for the accurate description of nuclear
systems, including dense matter probed in neutron stars. We explore nuclear
Hamiltonians that reproduce two-nucleon scattering data and properties of light
nuclei, but differ in the three-nucleon interactions among neutrons. While no
significantly improved constraints can be obtained from current astrophysical
data, we show that observations of neutron star mergers by next-generation
detectors like the proposed Einstein Telescope could provide strong evidence to
distinguish between these Hamiltonians.
