Description

As the simplest nucleus, the generalized parton distributions of the deuteron are highly desirable. These should be calculated in a manifestly covariant manner in order to ensure polynomiality, which is needed to allow extraction of the energy-momentum tensor. However, the Bethe-Salpeter equation is notoriously difficult to solve, with approximations usually breaking covariance. Thus, as an alternative to the usual approaches, a separable approximation of the nucleon-nucleon interaction kernel can be used, which is manifestly covariant but non-local. I will describe how a relativistic separable interaction can be constructed in such a way to reproduce existing precision wave functions in the non-relativistic limit, and present preliminary results for the electromagnetic form factors and collinear parton distributions of the deuteron in this framework.
