Query: Three-nucleon forces and nuclei at the extremes   Neutron-rich nuclei become increasingly sensitive to three-nucleon forces.
These components of nuclear forces are at the forefront of theoretical
developments based on effective field theories of quantum chromodynamics. We
discuss our understanding of three-nucleon forces and their impact on exotic
nuclei, and show how new measurements test and constrain them. Three-nucleon
forces therefore provide an exciting link between theoretical and experimental
nuclear physics frontiers.
