Description
Motivated by the desire to maintain manifest Lorentz covariance in calculations of deuteron structure, I model the nucleon-nucleon interaction using a non-local separable interaction Lagrangian. The Bethe-Salpeter equation for the deuteron's bound state vertex is separable and solvable in this model. With the deuteron vertex in hand, I calculate the electromagnetic and mechanical structure of the deuteron, which both receive significant contributions from two-body currents. I also explore the deuteron wave function in the non-relativistic limit, finding that good physical behavior at the origin imposes several constraints on the model parameters.
