Abstract

We study the three-body systems of ³He and pd scattering and demonstrate, both analytically and numerically, that a new pd three-body force is needed at next-to-leading order in pionless effective field theory. We also show that at leading order these observables require no new three-body force beyond what is necessary to describe nd scattering. We include electromagnetic effects by iterating only diagrams that involve a single photon exchange in the three-body sector.
