Three-Body Nuclear Systems in Pionless Effective Field Theory

Abstract

New perturbative techniques for three-body systems with contact interactions are discussed. Their application to pionless effective field theory (EFTπ$EF{T_{\not \pi }}$) for nd scattering is shown, and their extension to bound states addressed. With the extension to bound states a leading-order EFTπ$EF{T_{\not \pi }}$ calculation of the triton charge radius and novel treatments of three-body forces are discussed.
