- Title
Renormalized three-body equations with short-range forces.
- Authors

- Abstract
A three-body problem for a system of three nucleons interacting with short-range forces is discussed following effective field theory. Considering the case of a system of neutron-deuteron scattering, three-body equations are demonstrated such that the eigenvalues greater than unity are removed from the kernel leading to an equation that is renormalization-group invariant. The phase shifts are developed from a unique solution of the case of the doubled channel in neutron-deuteron scattering. The calculated neutron-deuteron phase shifts are well described below the deuteron breakup threshold.
